Help me with macro.

Hi.
I have very annoying problem :/ I want to make macro to normally cast Blind on my targets and when I hold shift+mykeybind to cast it on special player's name for example "Jorge" :)

I have something like this:

#showtooltip
/cast [modifier:shift][target=enemyplayername] Blind
/cast Blind

but it's not working :<

Please, please Can you help me ? :) I'm working on it for about 1h and still nothing :/

what is the key you are gonna use?

I'm using key H but I checked everything and nothing is binded on Shift+H :/

#showtooltip
/cast [modifier:shift, target=enemyplayername] Blind
/cast Blind

LE:
If it does not work in that format, use this:

#showtooltip
/cast [modifier:shift, target=enemyplayername][] Blind

You can change 'enemyplayername' with focus or arena1/2/3 depending on your needs.

#showtooltip Blind
/Stopattack
/cast [@arena2,mod:shift][@arena3,mod:ctrl][@arena1,harm,nodead][]Blind

something like this I guess.
it should work in arena with
nomod=a1
shift=a2
ctrl=a3
nomod out of arena=target

Thank you guys for your replies but nothing of these works :< but I fixed it :) I make something like this:

/target [modifier:shift,target=enemyplayername]
/cast Blind


And everything works perfectly :)
