The second script fails because of the line:
> set Folder1 to folder ("IBM 01:Users:parents:Desktop:Foo")
If this folder doesn't exist it generates an error. This error is caught by
the 'try' handler and your script drops to the (non-existent) error handler.
In other words the script doesn't get to the 'if not (exists...' line
because it was unable to get the folder in the previous script.
One way of rewriting this would be to:
