I am trying to build a query where the criteria is directly linked to a field in a form. This works except for one problem: I need the query to show all the results if the value in the field is 1. I have the following in there:
IIf([Forms]![fmStorageTransfer]![SupplierName]=1,Null,[Forms]![fmStorageTransfer]![SupplierName])
I need something else than "NULL", but nothing seems to work.
