How to make Animate custom animations play immedeately?

I made an npc and put the default "Animate" script in it ( i took the local script "Animate" from m character in test mode and turned it into a server script and also took out the chat part so it works), but i constantly need to change the anim ids, the problem is the old animations keep playing until something resets them, like the npc moving.

How can i make these animations be put immediately into effect? thanks
