@emskiphoto seems like the problem is you've got some unhandled character. this snippet seems to work in general but yeah, in no way does it have robust error-handling =/
sorry it didn't work for you, but it sounds like you did the equivalent thing manually. automation like this is really only useful when the problem is persistent. I for one, haven't used it since publication because the underlying problem bloating my notebooks was fixed.
