how to append URL parameter to redirect page ASP

The entire code is below, and the bit that appends the existing URL parameters is highlighted in red. If I comment that out, then the existing (undesirable) URL parameters aren't appended, which is good - but, I don't know how to create & append the two parameters that I do want - which are the ones inside the form on the page: UserEmail & SchoolEmailAddress.

I did manage to do this on the link for the SchoolName in the dynamic table, but couldn't figure out how to do it on the redirect URL. I can see there's a section to create strings for maintaining URL and Form parameters...is it something to do with this?

Many thanks.
