how to lookup different price codes

T

Thomas

Hello all I am working on a database for a small Tile retail store.
I could use some help on how to lookup different price codes.
Then place the amount into the Orders Subform!UnitPrice TextBox.

I have the user select from a Options Group Check boxes
Retail, Contractor, Dealer
--------------------------------------------------------------------------
Option Group PriceCode

Control Source = PriceCodeID
In the orders Table (FieldName PriceCodeID)
--------------------------------------------------------------------------
The CheckBoxes

Retail
Option Value =1

Contractor
Option Value = 2

Dealer
Option Value =3
-----------------------------------------------------------------------
Products Table

FieldName DataType Caption Name

ProductID = AutoNumber
ProductName = Text

1 = Currency Retail
2 = Currency Contractor
3 = Currency Dealer
----------------------------------------------------------------------

Orders_SubForm.Form Code


Private Sub ProductID_AfterUpdate()

On Error GoTo Err_ProductID_AfterUpdate

Dim strFilter As String
strFilter = "ProductID = " & Me!ProductID

(Look up product's unit price and assign it to UnitPrice control.)
Me!UnitPrice = DLookup("[1]", "Products", strFilter)
Exit_ProductID_AfterUpdate:
Exit Sub

Err_ProductID_AfterUpdate:
MsgBox Err.Description
Resume Exit_ProductID_AfterUpdate



End Sub

------------------------------------------------------------------

I replace the number 1 with 2
I get the Contractor Price


I replace the number 1 with 3
I get the Dealer Price

Can this be accomplished with Code ?

Any Help or other methods

Thanks in Advance

The way you have it set up, you want to change the field to look in
depending on the value of the option group. You will want to run the same
code in the AfterUpdate of the option group as well. The code below shows
how to do that.

Private Sub ProductID_AfterUpdate()
On Error GoTo Err_ProductID_AfterUpdate
Dim strFilter As String
Dim strField As String

'Look up product's unit price and assign to UnitPrice control.
If Not (IsNull(Me.ProductID) Or IsNull(Me.PriceCodeID)) Then
strField = "[" & Me.PriceCodeID & "]"
strFilter = "ProductID = " & Me!ProductID
Me.UnitPrice = DLookup(strField, "Products", strFilter)
End If

Exit_ProductID_AfterUpdate:
Exit Sub

Err_ProductID_AfterUpdate:
MsgBox Err.Description
Resume Exit_ProductID_AfterUpdate
End Sub

Private Sub PriceCodeID_AfterUpdate()
Call ProductID_AfterUpdate
End Sub

Since one product can have multiple prices, a better solution might be to
create a related table for the product prices. This ProductPrice table would
have fields like this:
ProductID Number relates to Product.ProductID
PriceCodeID Number relates to PriceCode.PriceCodeID
UnitPrice Currency how much each.
This would have several advantages, such as:
- able to cope with new price codes other than the 3 you thought of.
- able to get a price for the product even if the particular product doesn't
have the particular code.
- much more queryable.

Wow Allen thank you again for pointing the way.
I failed to note that the option group was on the main form.
Just as a follow-up final working code.


Private Sub ProductID_AfterUpdate()
On Error GoTo Err_ProductID_AfterUpdate
Dim strFilter As String
Dim strField As String

'Look up product's unit price and assign to UnitPrice control.
If Not (IsNull(Me.ProductID) Or IsNull(Me.Parent.PriceCodeID)) Then
strField = "[" & Me.Parent.PriceCodeID & "]"
strFilter = "ProductID = " & Me!ProductID
Me.UnitPrice = DLookup(strField, "Products", strFilter)
End If

Exit_ProductID_AfterUpdate:
Exit Sub

Err_ProductID_AfterUpdate:
MsgBox Err.Description
Resume Exit_ProductID_AfterUpdate
End Sub


Thank You
Thomas
