Go To Layout [//select a layout] should work with no trouble.
Original layout won't work as this takes you to the layout that was current at the time the script started.
If you need a 'back' button that will take the user to whatever layout they were on previously, use a global field or variable to store the layout name in the script that first takes the user to the error message layout.
Set Variable [$$LastLayout ; Get ( LayoutName )]
Then your "back" button can use Go To Layout [$$LastLayout] //use go to layout name by calculation option
To return to whatever layout was previous.
