Thanks Cristian, I also set up another test similar to what you have above and I've got it working! It was a problem with the format of the input, $filterQ. I had changed the separators and was exploding with the wrong symbol.. I mean, I had it all correct but had made another mistake in the syntax so I briefly changed things around to try to find the problem- just trying to juggle too many things at once I guess. Duh.
Many thanks though, I appreciate your help- you gave me confidence when I needed it!
