I'm trying to create a validation rule for an input field for a Nintex form and can't figure out how to do it.
Basically, I need the form to validate that the entry either starts with IS0, IS1, GP or BU (for 4 different types of projects). If it doesn't, I want to get an error
I've tried to even get a basic StartsWith working as a validation rule, but I can't seem to get it to work.
I've tried this as a starting point, but it didn't work.
not(or(startsWith("IS0", {Self})))
Anybody any idea what could be wrong here, and how to extend it out to include the other ID's as above?
Thanks for your help.
