OK, I hope my miriad of questions isn't bothering anyone, but when I get the bug about learning something new, I keep trying things until something works. Since I don't have anyone at work that knows MEL scripting, I've come to you all.
I'm making an install script that whenever anyone in my office needs the new tools I make, they can run the script. It works, so I'm trying to make it smart and it will only add the buttons that a person doesn't already have. This is what I've tried that doesn't work.
if (!`contextInfo -ex showImagePlane`)
Any know why it keeps installing the same buttons and how to get it to do what I want?
