Good Day All,
I need to control a "Single Line Text" to allow only 2 patterns.
To allow a user to only fill in a 3 digit number: eg. 001
or to in pattern. eg. "001-APP-01".
The numbers can be anything and the letters must be "APP" with the "-" between the letters and numbers.
I am new to regular expression so any help would be appreciated.
