Right Click give item

Hey guys!

So I need to make a simple mod that when I right click with any item in another player it transfers the item i´m holding to that player.

I´ve tried the blocks:

global trigger when player right clicks on entity

If is event/target entity subtype of player

               do add 1 item in main hand o f source entity to event/target entity inventory

                remove 1 item in main hand of source enity from sorce entity  main inventory

The item gets copied from my hand to the other player and them both get deleted.

What am I doing wrong????
