So this line here
URLRoot() & "db/bmgkazpqq"
specifies the URL where the table is located at.
you will see that the table ID one of your apps is located at mycompany.quickbase.com/db/bmgkazpqq
so when you click that button on your app or a copy of your app, it will go to that table - which them maybe in the wrong app f that code came from an original app and then you are now working on a Copy of the app..
The correction is to change that to
URLRoot() & "db/" & [_DBID_CHANGE_REQUESTS]
or whatever the "alias" table name is. You find that in the Advanced Properties for the table, down at the bottom of the page.
