VBA problem with SAP BPC report

Question

Hello
I have an EVDRE() SAP BPC report where one of the member id selection is derived using a VBA script. The problem I'm having is when I click on expand and refresh icon, the member id changes to #Value and the expansion and refresh fails as #Value is not a member id.
I would really appreciate any help on understanding why on expansion my VBA selected member id is replaced with #Value and how I can fix this if that is possible.
Many thanks

Thank you for your help with this problem which is now resolved.
Just to clarify we are on SAP BPC version 5.1
How it was resolved....
We had to use BEFORE_EXPAND as advised and also fix the calculation reference and finally also use AFTER_REFRESH.
We used VBA code to remember the dropdown lists option
and
copy the calculated member id into the pagekey dimension cell.
The AFTER_REFRESH restored the dropdown list option selected.
Not sure if the code is helpful but this is what we used....
Dim intRegionChoice As Integer
Dim intSegmentChoice As Integer
Dim intCountryChoice As Integer
Function BEFORE_EXPAND(Argument As String)
'Range(MCC_NodeToUse).Formula = Range(MCC_NodeToUse)
'Sheets("MCC").Select
'Sheets("MCC").Calculate
intRegionChoice = Range("AnswerRegion").Value
intSegmentChoice = Range("AnswerSegment").Value
intCountryChoice = Range("AnswerCountry").Value
Range("PickUpUserSelection").Value = Range("MCC_NodeToUse").Value
End Function
Function AFTER_REFRESH(Argument As String)
'MsgBox "After something"
Range("AnswerRegion").Value = intRegionChoice
Range("AnswerSegment").Value = intSegmentChoice
Range("AnswerCountry").Value = intCountryChoice
End Function
Thank you for all your help.
