I have a report that provides a list of all transactions and there details. I would like to sum a field within the report but restrict the items to to a field value that is within the parent form. In the code below I want the amount summed if the Drug = 'ACE' (this field is in the detailed record) and the TransactionType = 'Inventory Add'. Transaction Type is found in the parent but not in the detailed record. If I remove the TransactionType qualifier the summation works and adds up all the amount when Drug = 'ACE' so I suspect it is a problem with the TransactionType not part of the detailed record. How can I fix this?
=Sum(IIf([Drug]='ACE' And [TransactionType]='Inventory Add',[Amount],0))
