Thanks for quick response!

To the first: I'm not allowed to install them on my home directory, either. To the second: my reason is a version of "IT Reluctance"/"Manager Support". I'm most of the way through the script without the module, and so (unless for some reason this particular problem is entirely unsolveable otherwise) I'm going to do these few lines of code without it. I mentioned the modules because early in the project I read about the module, tried to get permission to use it, and could not.

In the end, though, my frustration is over the logic problem. Even copy-pasting the code fails to find a match, and clearly I must be doing something wrong in order for that to be so.
