Scratch

First of all ,sorry for any of you who have answered my posts before, but this is (probably) the last question I need answering so please answer!
Anyway, I am making a carnival game, and after every turn in my game, I need my shooter to change to another of the three shooters of your choice.
What you do, is at the beginning of the game, you choose between one of three coin shooters by clicking on one. Then the coin moves and comes back eventually, but, then I need the coin to go back to where it originally was, point forwards, deselect and, finally, let you choose another shooter.
This repeats until you run out of coins and lose the game.
Please help me make this happen!
I will be happy to do anything to get this sorted and will answer any suggestions, solutions, questions or anything else!
Thanks in advance!
