ColdFusion get current page variable and convert to link MYSQL data driven site

I have a data-driven site powered by ColdFusion and MySQL. I am building an update record page that starts as a dynamic table. Clicking on the record (link) takes the user to an update form. When I click the submit button, I want to go back to the page that I left. Currently it goes back the the first page. I can make it go to a specific page by using this as a link: <cflocation url="Update-List.cfm?PageNum_UpdateRecordList=2">

I want to replace the 2 with the appropriate variable. Using #CurrentPage# in place of the 2 does not work. So, how do  I get the page number that was passed to the address bar into something that I can use as a link?

My list is a standard dynamic  table run by a simple select statement. The link from the table to the update record form looks like this: <a href="updateform.cfm?ProductID=#UpdateRecordList.ProductID#">#UpdateRecordList.ProductID#</a>

<--Here is the coldfusion code from the update record form-->
