(GUI, Trig) Rune trigger and Spell problem

I'm trying to make a spell that uses runes. so far, i just made a spell based off of cluster rockets. i made it's casting time 1.5 seconds so the trigs have to time to work but the trigger or spell or something else is preventing me from letting the spell even work! my guy casts the spell but nothing else. the rockets don't fire. the trigger doesn't even work. i'll try to post more info later. so far, the runes work. the trigger for the spell is:
Event: Unit begins casting spell
Condition: spell equal to burning storm (my spell)
Actions: If: owner of casting unit controlls greater than or equal than 1 Fire rune and owner of casting unit controlls greater than or equal than 1 Wing rune. Then: Remove 1 fire and wind rune. Else: Order casting unit to stop and gives back mana used to cast.
I can't see no porblems.

nvm i want to delete this thread now... :/
