You must select at least one item!

The dropdowns for selection are available – but users are unable to select.

This means that they can’t click on the submit button as it won’t work. Have followed all of the instructions.

I can add the attendee using the admin function so the pricing and selection works in that view ( using the Add Attendee button.)

Using Version 6.00.31

In case it is relevant the security code ( captcha) won’t display either so have that turned off. ( Deactivated all other plugins & using 2010 theme.)
