Okay, first thing's first. Keep all your comments and questions in one post, this multiple post thing is annoying and might get you into trouble.
Second, to be able to color code something, you must first have the PMG Color Editor. Once you do that, you open a PMG with it, find the part of the PMG (by using something else, like the PMG Editor itself) and changing the thing in the drop down list to either the 1st, 2nd, or 3rd choices.
I can't really explain how to use the program very well.. but maybe someone could help you if you request a guide in one of the other sections?
