Problem with instances of movie clips

Hello there**!!

I am making a side scrolling game, and I am having issues with the “recollection of coins” part.
I created a movie clip called “coin”, and dragged and dropped 10 instances of that symbol to the scenario, I called all of them: “coin” (their instance names).

when the player jumps to get the coins, he just can get the first coin I called “coin”… If I try to get another coin, nothing happens… What am I doing wrong?

thanks a lot.

PLIP PLOP!!
