Moving a prim

Hello, I am trying to help a friend with something she is building and we are both very much unable to script at all. What she wants is a way to make a prim move on an axis back and forth which is turned on by clicking the prim then turned off when clicked again.

I am sorry if this question has been asked before but she would very much love to get some help on this problem.

Thank you

IM me in-world, I'll see what I can do. ^_^
