I just starting separating my data from my interface, placing the data in a separate data file. That said, I notice that any Auto Enter calculations (in the data file) that use the Self function must be edited to replace the Self function with the field name it refers to. Otherwise data entry in the interface file seems to ignore any use of the Self function. Is this to be expected, or am I missing something? I can kind of reaon out why this is taking place. I thought there might be a workaround that keeps the Self function in place.
