Opener macro

Hi there, long-time listener, first time caller.

So, I have a pretty decent macro that I use once I’m out of stealth, but looking for someone to make a castsequence macro that I can use for an opener. I’ve tried and can’t get it to work. It needs to look like this:

Shadowstrike, Nightblade, Shadow Dance, Shadowstrike, Symbols of Death, Shadowstrike, Eviscerate, Shadowstrike, Vanish, Shadowstrike, Death from Above, Shadow Dance, Shadowstrike, Shadowstrike, Eviscerate, Shadowstrike

Can anyone help me out?
