There are two ways of doing this. The easiest is to use the "navigate-" method described above by Ken. This method works great as long as the user always "Returns" back to the originating page via the "Return" (navigate -) button without changing to any other page in between.

If you want to be able to return to the correct originating page regardless of where and how many pages have been navigated in between you need to use the nested variable method. If you want to use this method email me (email is in my profile) and I will send you my file and explain the process. It gets a bit involved but would not be to bad with only four Fav pages. I have done it in my rcc with eighteen Fav pages.
