move up and down

Hello,

I want to make the shafts moving up and down all the time like in the capx file below.

http://dl.dropbox.com/u/52040403/up%20and%20down.capx

I tried the move to behavior to move the shafts up and when they hit their target position move them again down, but it's not working perfectly with me. Then i used the way shown in the capx file it works fine, but i need to repeated too many times.

Is there any other way to make the same movement.

Thanx :)

@Joannesalfa Thankx it's the correct way and that what i was looking for.

I tried the vertical sine behavior it works fine with me on firefox, but it doesn't on Internet explorer 9 "some of the shafts move vertical and some move horizontal even if i set their movement to vertical"

Thanx @Joannesalfa. Yes it works fine now.

Thanx again 4 ur help.

Have a nice day :)
