It seems that you have declared the object but did not set it, the error is refereing to "Report"

Add the following...

Dim Report As New rstoreinmaterial

Set Report = New rstoreinmaterial ''This line is new...

Report.RecordSelectionFormula = "{DetailsStore_InOut_Material.RepNo}= " & Val(RepNo.Text) & " and {DetailsStore_InOut_Material.projectno} = '" & ProjectNo1 & "'"

its still give the same problem :( , i installed the Crystal report 10 but i didnt usage is there is a relation between them ??

[AndreRet]

I doubt if there is a relation because the naming looks like someone who wrote the class code themselves. There must be function in your classes with the name rsstoreinmaterial that will handle all events for "Report". You need to make sure that it is in your application.
