Macro help

[StephenMB]

So I am trying to learn macros (thanks in previous post). Watched a ton of videos and pulled off a lot of them, but having issues with a basic attack macro to cycle through like 5 spells/CA's and then reset.

Let's just make it easy: Lvl 24 Hunter - I have available my pet, cobra shot, Kill Command, Barbed Shot, Bestial Wrath and Bite.

I just want a simple macro that casts all of those in some order as I spam my "1" key and resets when the target dies. Super simple, but for some reason I can't get spell/combat art abilities like this to work and it's killing me.... on either of my teams. Heal spells I can do no problem, but attacks they either stop if a spell/CA isn't highlighted and other stuff. Still have all my spells/CA's on individual numbers and now that I am headed into Dungeons I need to make things smoother heh.

And one thing that is confusing to me, if I do a cast sequence and list like 5 spells, if one spell isn't "active" and able to cast when it is it's turn, it seems to just sit there and wont go to next one if its' dark and stays there permanently. So for certain spells that need to be triggered by others, is there a way to make your cast sequence only cast it if it is "ready" and if it isn't it moves on to the next?

Thanks in advance and sorry for the noob question.
