That worked a treat! Thanks for the input, I greatly appreciate it!
A bit of background: I'm using this script as a tool to identify CV values above a certain percentage. There are a number of folks I work with that have JMP but not the level of experience that my self (and one other whom I work with) have, so by creating a script, I can give this to them and they can quickly and easily identify assays with CV outliers. It shouldn't need to be a dynamic filter since it's filtering for a hard cutoff. I just didn't want the data filter window sticking around for anyone to edit or offer up greater confusion. Many thanks for the answer.
