I would like to create a url button that redirects to the original location the record was opened from

I was drafting when a comment came in so I continue here:

Continuing to use rdr parameters and other crude redirection schemes will continue to hold back QuickBase's progress. In fact, the widespread introduction of redirection into formula URLs is probably one of the reason QuickBase did a reboot of their development plans. Using page redirection in formulas is preventing QuickBase from adopting a more modern "single page application" architecture.
