Need Help with SCH DPS Macro

[Beyondgrave]

I'm trying to make a macro so that I can dps while targeting the tank still but I'm having some trouble. Atm my macro look like this :
/ac "Cleric Stance"
/wait
/ac "Bio ii" <t>
/wait 3.0
/ac "Miasma" <t>
/wait
/ac "Bio" <t>
/wait
/ac "Cleric Stance"

But it some time would cast miasma and sometime it wouldn't. I could not get it to cast Bio 1 at all for some reason. Also, after cleric stance, there is a sec wait before using Bio 2. I try taking out the /wait command between cleric stance and bio 2 and that did not help. Also, i could not get it to cast Cleric stance once everything is done. Right now, I'm using <t> to test it out in the open world before I start using it in group contents.

So I changed it to :
/ac "Cleric Stance" <me>
/wait 1
/ac "Bio II" <t>
/wait 3
/ac "Miasma" <t>
/wait 2.5
/ac "Bio" <t>
/wait 1
/ac "Cleric Stance" <me>

and got it to work. but the problem now is that it work the first time casting, but when I cast it again, it would skill bio 2 and go straight to miasma and then bio and the cleric stance. Any idea how to fix this? any help is much appreciated.
