I've been struggling with this. I had it working at one point, but now can't seem to get it to work. All I'm trying to do is hide a column when a button is clicked. As I said at one point this was working, but now I can't seem to change (or even find) the rules for this style. I can get to the style, and know it exists, but the rules don't seem to. The alert always gives me a null value, the first time I click, then I see "inline", but the column doesn't show up.
