Help me out here????

[rab12]

Got a question... I was playing with just the normal munchkin set and was at level nine. I was tied with the monster I was battling and had a help me out here card in my hand. I played it and wanted to know if I could use the help me out here card to take an item from the carried (backpack) area on the opponents side? The card I chose was the doppleganger which would have given me the victory. Thanks for your help.
