I have edited this code thanks to the lovely comment below but I get the same
error saying as below.:

Message: stale element reference: element is not attached to the page document

I roughly understand why this message shows up but still have no clear idea on
how to fix this. I would deeply appreciate any comment! Many thanks in
advance!
