I'm new to all this and have tried entering validation into my form unsuccessfully.
I have a field in my form which is essentially a flight number and I need to have it validated to stop incorrect data being entered. The field must be entered using a combination of alpha and numeric characters.
Example: TCH1401, QF201, BA415 ANA2315.
What I am trying to stop being entered is any of the following characters being entered as part of the data as this is incorrect and requires editing and correcting:
Non allowed characters, / : \
TCH (Without proceeding numeric values)or any Alpha combination without numeric values
1111 (Numeric values entered that don't start with alpha)
If anyone can assist me with this I would really appreciate it, I read the help notes on validation unfortunately that didn't help and just made it more difficult to understand, as it only deals with generic scenario.
Cheers
Peter
