I followed the directions in the FAQ181-5497
Simply add to the Tag Property Where=tblEmp.lngDeptID,Number;. That's all there is to it.
But you say to put in - where [Value that you didn't specify] = [Invoice Data Entry].Month
If I am using a Listbox isn't this the [Value that you didn't specify] when I make a choice?
I had to do the following to get it to work. Thanks for you help; Where=[Invoice Data Entry Monthly].Month,String;
