Vertical and horizontal moving platform problems!

Hi, I am in the finishing stages of my first game, yeeah! I really love LUA and Corona but sometimes it's easy to get stuck and now i am there again :)

I am having platforms in my game that moves in two directions. Both horizontal and vertical. I managed to get the player on to those platforms when it moves and so far it is ok. I am also using physics for my game and I think that it did not get easier with that - but on the other side the gamefeeling is awesome!

Problem

When the player is traveling on a platform that moves vertical, he doesn't jump of the platform? It works perfect on the platforms that moves horizontal? I am using levelHelper for creation of levels, you will see some code I am using to interact with objects in my code.

In my collision routine I have this code to see if the player is hitting a moving platform:

elseif event.other.lhTag == LevelHelper_TAG.MOVING then
 
        --=======================================================
        -- MOVING PLATFORMS
        --=======================================================
 
                if (attachedPlatform==false) then
                        --Create an instance to the moving platform
                        ActivePlatform = loader:spriteWithUniqueName(event.other.lhUniqueName)
 
                        --Check that collision occurs on top of platform
                        if (ActivePlatform.y - ball.y>12) then
                        
                                --Offset of player and platform
                                PlatformOffset = ActivePlatform.x - ball.x
                        
                                --Check that the player hits inside the platform and not on edges.
                                if(PlatformOffset>-40 and PlatformOffset<40) then
                
                                        --Change tag on sprite to avoid any more collisions right now....
                                        ActivePlatform.lhTag = LevelHelper_TAG.DEFAULT
 
                                        --Player can jump
                                        ball.jumping = true
                                        --player is attached to the platform
                                        attachedPlatform = true
                                end
                        end
                end
                
else
        ball.jumping = true
end
