Text Input Validation

Hi, I’m creating a page where a member of our Amateur Radio club needs to input his Callsign, once I’ve validated the validity of the call sign, I will then search the MembersDB for his callsign and then publish the member’s data.

But in trying to sort out the validation i started of with basic validation process and the validation message keeps returning “value missing”


see code below
