Merry Christmas and a Happy New Year to you too!
In my opinion, you don't need variables in order to do what you want. It would save time to simply make your favorites pages devices, either as pages under your SKY+ (one for RF and one for TAG), or as devices themselves (one for RF and one for TAG). This way, you have one dedicated to each mode, then you can control the volume for each accordingly by setting the appropriate vol and ch punch through.
Let me know if that works for you.
Thank you,
Damon DG
