Hi, im looking trying to make a field text[6] with an allowed input format saying 2 letters, a hypen and the 3 letters/numbers.
Example: "DE-AB1"
How do I make the Onvalidate code?
Do I need to make 3 variables:
1. 2 letters
2. The hypen
3. 3 letters/numbers
Or can I make it all in one go?
Have tried some different ways but it wont work.
Thanks in advance.
