Hi Everyone, I got a problem with the Regular Expression Validation of custom fields. I have set the following regular expression in a custom text input field: ^[A-Za-z0-9._\-]+@{1,1}[A-Za-z0-9._\-]+\.[A-Za-z]{2,3}$ When I submit a ticket and fill in 'test@test.com' in this custom field I get the following error for the field: 'One of the required field(s) is empty' I tested the same expression in a simple php script with the ereg function and it works without a problem. Anyone knows what the problem is? Thanks & regards Lokananth
