Problem with my macro

Hello everyone, I only recently started trying to use macros which i think is important in game skill enhancement. So i was trying out a macro for my hunter that i made and it works perfectly fine but the problem is it does not show the tooltip. Here is the macro i am saying.

#showtooltip
/cast [mod,@mouseover,harm,nodead][mod,@target,harm,nodead]Multi-Shot;[@mouseover,harm,nodead][@target,harm,nodead]Arcane Shot

can someone please help me with this. I tried searching the web for anything that can help me but i can not find one. It would be nice if someone can help me.

P.S.
I am sorry for my bad English.

what Icon shows this macro at the moment?
and what Spell tooltip would you like to show? If both spells then i do not know, but meanwhile if you add the spell name next to #showtooltip it will shows that one, example:
#showtooltip Arcane Shot
Or
#showtooltip Multi-Shot
Better than nothing
