Using ranges with Visual Basic, stuck...

I am having issues with some Visual Basic code I am trying to make. My issue
is that I am used to coding with C and other languages (long ago) and I am
not sure where I am going wrong here. I pretty much only have this discussion
group and various Microsoft documentation at my disposal which has been
helpful.

Purpose:
- The purpose of my program is to look at a "Begin Date" which is inserted
into cell "I3" of the worksheet "1.3 - AN - Total Consumption" and then
beginning to compare that Date with the dates listed in Column A of the
worksheet "1.2 - AN Amounts".
- Once the proper ROW is found in which that date occurs, I want to begin
transferring specific cell data, row by row, from worksheet "1.2 - AN
Amounts" to worksheet "1.3 - AN - Total Consumption".
- I want this to occur until I reach an End date as specified in cell "J3"
of the worksheet "1.3 - AN - Total Consumption".


Example of Cell Update (from "1.2 - AN Amounts" to "1.3 - AN - Total
Consumption"):

A10 -> A3
B10 -> B3
H10 + I10 -> C3
E10 -> E3
G10 -> G3

Then, for the next loop:

A11 -> A4
B11 -> B4
H11 + I10 -> C4
E11 -> E4
G11 -> G4

etc...


Here is my code:

Code: 
Private Sub update_data_Click()

' setup variables
Dim range1 As Range, range2 As Range, range3 As Range, range4 As Range '
relative ranges
Dim current_date As Date, current_end_date As Date ' date variables
Dim continue As Integer ' integer variable
range1 = Worksheets("1.2 - AN Amounts").Range("A3")
current_date = Worksheets("1.3 - AN - Total Consumption").Range("I3")
current_end_date = current_date + 6
continue = 1

' find location of current_date in "1.2 - AN Amounts"
While continue = 1
range2 = range2.Offset(1, 0) ' (RowOffset, ColumnOffset)
If range2 = current_date Then
continue = 0
End If
Wend

' reset continue counter
continue = 1

' offset ranges
range3 = range2.Offset(-1, 3)
range4 = range2.Offset(-1, 5)
Worksheets("1.3 - AN - Total Consumption").Range("D2") = range3 + range4
'total AN remaining

' place all information from begin week to end week
While continue = 1

' checks to see whether the end week is reached
If Range("J3") = current_date Then
continue = 0
End If

' cell update
range1 = current_date ' Start Date
range1 = range2.Offset(0, 1) ' End Date
range1 = range2.Offset(0, 7) + range2.Offset(0, 8) ' Weekly AN Taken
range1 = range2.Offset(0, 4) ' Recieved LD AN
range1 = range2.Offset(0, 5) ' Recieved HD AN

' update value for current beginning and end dates
current_end_date = current_date + 6
current_date = current_date + 7
range1 = range1.Offset(1, 0)
range2 = range2.Offset(1, -5)

Wend

End Sub

For starters, where is range2?

Your code line:

range2 = range2.Offset(1, 0) ' (RowOffset, ColumnOffset)

You can not reference "range2.Offset..." until you've set a reference to
range2!

That is my mistake. These are the two correct ranges:

range1 = Worksheets("1.3 - AN - Total Consumption").Range("A3")
range2 = Worksheets("1.2 - AN Amounts").Range("A4")

I am having issues with some Visual Basic code

What sort of Visual Basic, eg .Net, VB/A

If VBA or classic VB you need to use the 'Set' to assign objects, eg
Set range3 = range2.Offset(-1, 3)

you declared "range1 as Range" but what do you expect of this -
range1 = range2.Offset(0, 7) + range2.Offset(0, 8)

to assign the sum of the two cell values ?

Ah I see it must be VBA otherwise you would have done
Dim range1 As Excel.Range

I haven't tried to follow your code.

Add "Option Explicit" without quotes at the top of your module, put the
cursor in the routine and step through pressing F8

Peter T

It is whatever Visual Basic is built into Office 2007.

Microsoft Visual Basic 6.5
VBA: Retail 6.5

OK it's Visual Basic for Applications, VBA.

Refer to the rest of my post.

First, when you're working with objects (like ranges, workbook, pictures,
worksheets, ...), you have to use Set:

Set range1 = Worksheets("1.2 - AN Amounts").Range("A3")

If you use:
range1 = Worksheets("1.2 - AN Amounts").Range("A3")

it's the equivalent
to
range1.value = Worksheets("1.2 - AN Amounts").Range("A3").value
(and range1 has to be set to a range before that happens).

I have no idea if this does what you want, but it compiles ok:

Option Explicit
Private Sub update_data_Click()

' setup variables
Dim range1 As Range
Dim range2 As Range
Dim range3 As Range
Dim range4 As Range

Dim current_date As Date
Dim current_end_date As Date
Dim continue As Long

Set range1 = Worksheets("1.2 - AN Amounts").Range("A3")
current_date = Worksheets("1.3 - AN - Total Consumption").Range("I3").Value
current_end_date = current_date + 6
continue = 1

' find location of current_date in "1.2 - AN Amounts"
While continue = 1
Set range2 = range2.Offset(1, 0) ' (RowOffset, ColumnOffset)
If range2.Value = current_date Then
continue = 0
End If
Wend

' reset continue counter
continue = 1

' offset ranges
Set range3 = range2.Offset(-1, 3)
Set range4 = range2.Offset(-1, 5)

Worksheets("1.3 - AN - Total Consumption").Range("D2").Value _
= range3.Value + range4.Value
'total AN remaining

' place all information from begin week to end week
While continue = 1

' checks to see whether the end week is reached
If Range("J3").Value = current_date Then
continue = 0
End If

' cell update
range1.Value = current_date ' Start Date
Set range1 = range2.Offset(0, 1) ' End Date
range1.Value = range2.Offset(0, 7).Value + range2.Offset(0, 8).Value
Set range1 = range2.Offset(0, 4) ' Recieved LD AN
Set range1 = range2.Offset(0, 5) ' Recieved HD AN

' update value for current beginning and end dates
current_end_date = current_date + 6
current_date = current_date + 7
Set range1 = range1.Offset(1, 0)
Set range2 = range2.Offset(1, -5)
