Help needed on adding animation thru scripts

Hi all,

i've made a character and many animations for it. for the default animation (root, run) they works fine.
but i wonder how to add my own animation to the character.
i've tried adding a keybind in client>default.bind.cs. the script works since it echo the mouse click. but the animation doesn't play. have i do something wrong??
i've the dsq file and wonder can i add the animation via scripts or i have to do something to the engine via source code?

i'm no programmer so i do hope i can do it via scripts.

thanks all,

simon
