How do I stop player momentum when on a ladder?

I used this tutorial here to add a simple ladder to my game:

scirra.com/tutorials/591/a- ... latformers

However, when I jump on to a ladder or fall on to a ladder, vertical momentum is retained and the player slides up or down the ladder without player input.

How do I stop this from happening?

I've attached my .capx so you can have a look.

Thanks very much. I set MaxFallSpeed to 0 instead of setting Gravity to 0 and it worked a treat.

But now I have a different problem. The character will not animate while climbing the ladder up and down, but it *will* animate if the character is climbing the ladder and moving sideways.

Any ideas?
