How do I stop the player from jumping?

I have a platformer behavior on my playable character but I don't want him the have the ability to jump. How would I take that function away.

easiest way - set jump strength in properties panel to 0 ( select (left click) player sprite and in left side panel)

Thank you, the crazy part is I just thought of that after the post and realize how much of a noob question that was lol. But thanks for the quick response.
