Thank you for reply....

I understand what you mean but does the PayPal module really need said details? As i have advised my new customers to enter dots in these boxes and everything works ok.

My shop only requires users to log on, everthing else is taken up by PayPal's website which has those details. So i can't see why the Z-Cart module would use them.

I would have thought that having a maxium value for the boxes of zero at sign would end the need for input however, sign up users get a form error if nothing is entered.
