Hello, 

I would like to add a constraint in Quick Fields for a Student ID field and the first 2 characters are letters and the remaining 5 characters are numbers. 

Please advise what I should enter in the Constraints Dialogue box.

Please note that I am following a training video and in that example, they used Student ID field with 7 digits. (See screen shot below for support).

The pattern used was \d\d\d\d\d\d\d

I would like to know what is pattern for the expression when the first 2 characters are letters and the remaining 5 characters are numbers?

Thanks!
