Dear experts -
This should be an easy one -
I want to see if a record is selected in a continuous subform.
The code below was working fine, except that if NO RECORDS appear under the current filter condition:
If IsNull(Me!sfPartsLines.Form!txtExpense_ID) Then
MsgBox ("Please select an expense item first.")
In that case, I get the error "YOU ENTERED AN EXPRESSION THAT HAS NO VALUE"
