i was wondering if some people could help me with some mage problems

here are some basic addon i need help with

sharing/accepting quest
turning in quest
drinking/eating

here is my mage problem

sometimes when i use my assist macro, all my second mage does is stand around and not help, i dont understand why that happens since every now and then it works


and i got some weird script from a dude thats kind of buggy so does anyone have a script link or something?
