How do I combine two scripts into one?

Rather than combining these two, just try my script. It offers a lot of functionality. I made it for a friend that wanted a progressive gride for some test that he was doing for a book. It also lets you save presets for different grids.

Here is a sample of what the script does. I combined to images into the one. The bottom blue has a additive progressive gride along the width. You can change the line spacing and size. You can also include guides.
