I made an attribute that calculates the width of each side of my cylinder.
its stored as an attribute called "globalWidth"
I want to make a chf that is connected to this globalWidth so I can reference it.
chf("globalWidth",0) does not work and I dont know how to make a chf that updates.

You can't reference that using chf because it's not a channel. Here's a file with a couple of ways you can reference it, using expressions or VEX

I should add by the way that once you've referenced the attribute with a point expression, you CAN reference that using ch. So in that scene you can use ch("../box1/sizex") to get the channel value.
