Using Access 2002:
I have created a dynamic crosstab report based on one from a KB article
(http://support.microsoft.com/kb/328320) which is working great for me.
However I have come up against a problem...
Currently the row totals column and the column totals in the report footer
do exactly that - display TOTALS. I would like them to display averages
instead. This causes me various problems: 1. The column count is not always
the same - it could be anywhere between 3 and 9 (including row headers and
row totals, i.e. showing 1-7 days of data). 2. Sometimes the vaules will be 0
- I want to exclude these values from the average calculation. 3. This all
goes slightly beyond my VBA abilities!
I've attached the code for the report, which is adapted slightly from the
code in the KB article:
Option Compare Database
' Constant for maximum number of columns
Const conTotalColumns = 9
' Variables for Database object and Recordset.
Dim dbsReport As DAO.Database
Dim rstReport As DAO.Recordset
' Variables for number of columns and row and report totals.
Dim intColumnCount As Integer
Dim lngRgColumnTotal(1 To conTotalColumns) As Long
Dim lngReportTotal As Long
Private Sub InitVars()
Dim intX As Integer
' Initialize lngReportTotal variable.
lngReportTotal = 0
' Initialize array that stores column totals.
For intX = 1 To conTotalColumns
lngRgColumnTotal(intX) = 0
Next intX
End Sub
Private Function xtabCnulls(varX As Variant)
' Test if a value is null.
If IsNull(varX) Then
' If varX is null, set varX to 0.
xtabCnulls = 0
Else
' Otherwise, return varX.
xtabCnulls = varX
End If
End Function
Private Sub Detail_Format(Cancel As Integer, FormatCount As Integer)

' Put values in text boxes and hide unused text boxes.
