Validate unique string on Sign Up

[bell.jeremy.robert]

Hello,

I’ve created a sign up that generates a unique string. I’d like to only submit the form if the unique string does not already exist in the database, but I can’t figure out how to reference this string in ‘Only when’.

Any help is appreciated

You can’t… (as it hasn’t been generated yet)…

You’ll need to generate the string first (such as in a custom state), then use that value in both the User sign-up fields, and the conditional.
