What steps will reproduce the problem?
1.  I switched "Bar texture" to "Blizzard Character Skills..."
2.  I switched "Class color bars" to off (unchecked)
3.  I switched "Class color text" to on (checked)

What is the expected output? What do you see instead?
I am not sure what it is supposed to do, as it failed to work when I tried it, but I expect that the bars should switch to one uniform color and the letters and numbers on them should change to class colors.  Instead it stayed the normal colors for each bar and white for the text, and a LUA error popped up.  It popped up again when I reverted the two "Class color" options.

What version of the product are you using?
r457

Do you have an error log of what happened?
