My phone info is in a text field and there is no format for phone numbers,
only date/time. I can't apply an input mask after the fact.
And in what country's format?
This group has readers all over the world.
In the US we have many different formats, i.e.
123.456.7890, 123 456-7890, (123) 456-7890, 456-7890
In what format would you like to display the number?
And do they all include an area code? Or not?
By the way, you can apply an input mask after the fact in a report.
It will display the phone numbers in the report the way the mask is
set up, but it will not change the actual data stored in the table.
