Bar Help?

Hey,

I'm having some major problems with the bar feature of my character sheet.

I want to:

Change the color of the bar.
Change the size of the bar

But, whatever I do, it doesn't seem to work. I tried editing the bar color, but it only affected the text next to it. I tried changing the settings in the fields style under my bars, but they seem to make the bars dissapear.

Can anyone help me with these issues?
