This code shouldn't return an error never, unless "theText" is an undefined
variable...
Perhaps (?) theText is an undefined variable or some labeled object within
your project? I think the best way to debug an error is know the error ;-)
Why don't you handle the error properly, so we can see what is it?
try
...
on error x
display dialog x
end
