Form Validation - if value already exists
I have the SuperSuite, and I'm wanting to validate a particular form field to make sure that the entered value doesn't already exist in the database.
I know that I can go to the Server Behaviors panel choose WA Validation Toolkit > Server Validation, but it doesn't seem like it has the option I'm looking for.
Does that really not exist, or am I just blind?
I just realized that I put this thread in the eCart forum... sorry about that, can somebody move it for me?
