Problem with Hidden Cells

For some reason I'm not able to get columns to hide in a workbook through a macro. I don't get any error messages, it just doesn't hide the cells. I've used this code multiple times, but for some reason I can't get it to work. I first reset all the hidden columns in case some wrong ones are hidden, then I hide the correct cells. This isn't the first time I've done this particular code, but it's the first time since I first used it I've had any problems. Maybe it's something simple and I just can't see it. Can anybody see what's wrong with this code?

Never mind, just figured it out. I had an autofit code below this, which just negated hiding any columns. Just had to move it above this set of code, now it works fine.
