I am trying to put a new scope sprite in from FPS Bananas and I am making the new sprites folder after Steam/Steam apps/Day of defeat source/DOD/materials/sprites/scopes, but it does not work in the game. What am I doing wrong? Do I have to activate it somehow?

A guy last night told me to activate before the game starts up..
Do you have to do something with the console commands?

I am also looking for the console commands to give people health and take away health.

Please let me know. Your help would be greatly appreciated.

Thanks
Field
