Thank you very much, Norm, appreciated.

Are these variables maintained from page to page? I mean, the $_Request
goes on the second page, while the form fields are on the first, correct?
Can I continue advancing pages with the same variable names? Or do I need
to declare them on each page? My intent is to use the chfeedback php script
to email the form field data and results to an email address.

In terms of syntax, these { } are always supposed to enclose the seting of a
variable value? Or am I oversimplifying their purpose?

Thanks again, that was very helpful.
