Could you tell me where I'm going wrong "First Timer"

Good Afternoon,

I wanted to say firstly how much this will help me and my 6 digits as there are far to many keys for them :).

I’ve watched a video online on how to make a macro and also had a look at a few others.

I’m trying to make it so When I come out of stealth I Garrote an npc then cast Cheap Shot as I have the talent that lets you cast stealth ability’s within 3 seconds of coming out of stealth. So far it is only doing one of the other.

Please see my attempt:

Key Press =
/targetenemy [noharm][dead]
/cast [stealth] Garrote
/cast [@focus,exists] Tricks of the Trade

Sequence=
/cast [nostealth,nocombat] Stealth
/cast [stealth] Cheap Shot
/cast [combat] Vendetta
/cast Toxic Blade
/cast Mutilate

Thank you for any information on where I’m going wrong. I’ve been testing this on a dummies in the city’s as I’m currently at work and cant test it on npc’s

If anyone has any good learning macro links then I’d also be very grateful.

Thanks for any help but this has now been resolved.
