Macro trouble

[Rainflush]

So, I've perused a number of threads about macros now though for whatever reason I can't get a threat reduction macro working for my rogue.

The macro itself seems simple enough:

/attack off
/doability x (hide)
/attack on

The problem is the /doability part, I'm guessing I don't understand how that works because I've been moving my "Hide" button all over my hotbar (the idea being the ability is in slot X so /doability X will activate it) but the macro won't make the button depress, it basically just enables autoattack. What am I doing wrong here?
