Player animations not working?

I’m setting the players model to t_leet.mdl from Counter Strike but it seems like animations aren’t working. (No walk anim, shoot, etc. Basically his arms are out to the side like you would expect a source model without animation to look.)

On another note, what name should I type in for CS:S weapon? Example(which I know doesn’t work): ply:Give(“weapon_ak47”)?

Are you using the player model or the NPC model?
