Validation Regex is not working

[Prudhvi Raj4]

Hi Team,

I have created a Validation Regex for the one of the single line text variable, but it was giving error when I enter the correct expression as well. I am checking for alphanumeric with hyphens in between. Below is the code using.

Result form above validation

Error popping up for correct values as well.

Thanks,

So close - use [] instead of ()

^[a-zA-Z0-9\-]*$

Hi @Brad Bowman  

Yes, I have already tried it, so the result was, It was expecting any type of expression. If I give only number only no error and system takes it as correct expression

So what is your actual requirement - a certain number of alphanumeric characters PLUS a hyphen?  Must/will it always be 4-4-4-4-4-4 as pictured?

My Requirement is the field should have 24 characters alphanumeric value with a hyphen after every 4 characters 

Example: Ab12-CD34-fg45-Sf45-s1ft-1We4
