Specific Validation
+6Hello community!
I need to make a custom validation to an open-ended feedback box for a specific format. I am asking people to submit their employee number which has the following structure:
* Is exactly 4 characters long.
* Is alphanumeric
Anyone know how to do this? Mainly I want to make sure people put exactly 4 characters in to the text entry box.

Hello @Akdashboard ,
Use the below regex in custom validation
`^[a-zA-Z0-9]{4}$`
