help plz... need this pretty bad

Arghhhhhh i need help!!

i need to know, how can i do it, so when i use an item from a shop... it then allows you to create a certain unit in the barrakcs Ect.

for example...

if say i use an item called Train Taurens... when u use this item, it allows you to create taurens at your barracks.

tnx in advcne

make the item usable (like a potion), create a reaserch named "Train Taurens", and create a trigger:

event - a unit uses an item
condition - item type of (manipulated item) = (Tauren research item)
actions - set research level of (Train Taurens) to 1 for owner of (triggering unit)
(i think triggering unit will work)

if this works, dont say thank you in a post. say it by doing what my sig says.

Hmmm... when i use it, it say's your hero is at full health, and i cnt use it. so is there a way to sort it?

dont base it off a healing item, use a different item type, i.e a haste scroll and set the duration to .01.

or you could use a tome that doesn't increase stats because tomes are used as soon as picked up

alright tnx alot people i found it out... +reps

also... one more question, i have my shop so its a hidden mountain giant, yeah a giant hidden O.o but it is... but the only problem is, it shows up on the map as a small square because of it being a building. how do i take the square off if u can!

somewhere in the object editor, there is a field that says 'Show on mini map' or something like that. make sure it is false. there are two similiar fields, so make them both none cause I don't know which one does it.
