in cases where you don't want the variables to carry over, you could just make a ring that calls the other two rings.
in this case though, you're using variables across the two scripts, so you want metaprogramming.
here you can SPLIT both by blocks, then JOIN them (both blocks are in operators). i think in some cases you need to append them instead, or do other things.
i'd suggest splitting all 3 of those by blocks and see how they look to get a feel for it.
note that since script 2 is already in a ring, you could also just add a as a parameter to the ring instead.
