Regular Expressions for Study ID

Hello, I would like assistance in generating a regular expression for a Study ID which can take the following formats:
K-XXXX-IPD
K-XXXX-MOPD
K-XXXX-AE
Where X is a number i.e. K-1234-IPD, K-1234-MOPD, K-5432-AE

Thanks a lot!

Hi @kabalaandrew
something like this probably:
^K-[0-9]{4}-(IPD|MOPD|AE)$

just to explain:
^ the beginning of the text https://javascript.info/regexp-anchors

K- which is your static value

[0-9]{4} numbers from 0-9 used 4 times

- static value

(IPD|MOPD|AE) IPD or MOPD or AE
