Wrong Event for "Used" item

[ShadowInTheD]

I need an event to detect when I "Left click on this item"

Apparently, "a unit uses an item" doesn't work; maybe it's because I made it an active item with no ability or something?

How can I fix the item (without recreating it) or fix the event?

It needs a ability. Make a instant no target ability and make it set to the item
