How Could I Edit Animations?

So I'm fairly new to animations in ROBLOX. But I need to know how to change the jump/walk/fall etc. animations. I used the plugin and editor, I'm ready to go. Except I need a script for all the animations and how I can change them. I didn't understand the wiki tutorials, so can somebody please help?

The character (someone inside of workspace) has a localscript called Animate inside of it. Inside of that you see all the animations along with the a child as the actual animation which plays.

--To find and change certian animation
player.CharacterAdded:connect(function(char)
	char.Animate.fall.FallAnim.AnimationId=(http://www.roblox.com/asset/?id=180436148)
	--this will set it to the defualt
end)

You can see the names of all the animations by playing your game in studio and in explorer finding your character, inside of that the Animate localscript, and inside of that all of the animations.

Hope this helped!
