Problem

Can anyone supply me with the coding for a pickup that can only be activated once then it disappears from your inventory, the effects last until you die, it increases the player speed and makes a CloakUp sound when activated?
I've been trying to get it to work for ages, I've tried many different strategies in the script, It either doesn't compile or doesn't work. It's been annoying me for ages. Not even Bowen could get it to work.
