I had a problem with the pop up not working in IE. But Piotr Moćko the creator of the pweb form was a tremendous help in sorting this out for me personally.
He even got the fill-in boxes to align right for me on the picture of the girl wearing the headset.
I have put this form on a website that is taking orders for wedding cakes.
All you need to do is put the owners email address into the appropriate field in the backend of joomla and they get the details of the enquirer. Easy!
For £8 I think it was, it's a steal. Nice one Piotr Moćko
