first a good advise to those who create Custom Functions: test them in the Data Viewer before using them in a calculated field, in a table that has 4700 records. How do I know ? Ya, you guest it .
Since it's going to take forever, I force quit FMPA to end the torture, thinking I could the get back to my file and correct the Custom Function... Well when I reopen the file, FMPA remembers its was updating a calculated field and restarts the process.
Is there some way I can have FMPA forget about the calculated field and let me work with the file ?
