Stacking or Overlaying Fields
I am drawing a blank on something I used to know. Since FMPro does not have a masking for telephone numbers, I know there are numerous techniques for this. An older technique was to have the number in a field as the straight digits, no formatting. Then a second field was used to calculate the format. It would look like one field to the user. If they needed to edit the number it was done in the unformatted one.
I have searched the forum for the answer. I have googled it. No luck. I thought it was referenced in Filemaker & Me, but reading it again I did not find it.
