When either edit_record.cfm or email_review.cfm loads, set an input type="hidden" field called "returnTo" and give it a value of #cgi.script_name#. After the database stuff, CFLOCATION to that form field value.
Regarding, "What i want to do is to have a have my cflocation go to any of my previous pages"
You can't. You have to go to a specifc page. If there is conditional logic involved, that's a different story. Also, if you want to pick a previous page at random, that's also possible although it seems rather silly.
If you want it to return to the page that called it try this:
the referer is the page that called your current page.
if you dump the <cfdump var="#cgi#"> you will find all sorts of goodies in there.
