Check Username- How?
I set up a simple customer database (to be used internally in my office) using DataAssist. One of the fields is email. I want to prevent staff from entering a customer with an email that is already on the system. So, I want to insert a new customer, but i want the system to check if this customer already exists by checking the e-mail. When I use Dreamweavers 'check new username' it pops up the following message " This server behaviour requires the presence of the Insert Record behaviour on the page. Add an Insert Record behaviour and try again.". So how can I 'check new username' with DataAssist - in order to prevent duplicate enteries?
