Test for numeric on imported data
When importing data I want to test whether a given field is enterly numeric or whether it contains any non-numeric characters. If the data is numeric, I want to simply allow its entry, and if it is not numeric I just want to set the receiving field to zero. This seems very easy in other applications but I am having trouble with doing this in FMP 12. I do not want any dialog or other interuptions in the import process.
