>>>Well, I put it on and ended up with a bunch of errors where I would no longer be able to do things like:

>>That's what it supposed to do. It's complaining because you are attempting to apply the Trim() function to a type that may not be a string - a source for potential exceptions. If you are sure the toRow("Table") is indeed a string then you can make the compiler relax by doing an explicit conversion. You could, in practice, still end up with the error - but it would be entirely your fault :-}
