Skip page numbers in a branched section

I want to include a branch section in my Captivate, but after the branch, I want the slide numbers to skip those slides and resume from the branch menu. Example: Branch menu is on slide 22. I have 2 branches. I want the page number to skip the branch slides, and be the consecutive number from the branch menu. Branch menu is slide 22, I want go directly to the Summary, (which is actually slide 30) but I want the page number to be 23, and then continue consecutively after that. Currently I am using the variable cpInfoCurrentSlide for my page numbers. In the branch, I used an advanced action to increment/decrement the section page numbers.

Also, is there a place I can reference what the system variables actually do?

Thanks
