Grief Friendly Fire Help in Scripting

I'm trying to add grief fire into world at war. When you shoot players, it slows them down and when you knife them it pushes them. This is what I have so far from somebody else but it doesn't do anything currently.

Code Snippet

Plaintext

Callback_PlayerDamage( eInflictor, eAttacker, iDamage, iDFlags, sMeansOfDeath, sWeapon, vPoint, vDir, sHitLoc, modelIndex, psOffsetTime )
{
	//CODER MOD: TOMMY K, this is to prevent a player killing another player
	if( isdefined( eAttacker ) && isPlayer( eAttacker ) )
	{
		if( self != eAttacker )
		{
			self thread griefing( eAttacker ); 
			return;
		}
		else if( sMeansOfDeath != "MOD_GRENADE_SPLASH"
				&& sMeansOfDeath != "MOD_GRENADE"
				&& sMeansOfDeath != "MOD_EXPLOSIVE"
				&& sMeansOfDeath != "MOD_PROJECTILE"
				&& sMeansOfDeath != "MOD_PROJECTILE_SPLASH"
				&& sMeansOfDeath != "MOD_BURNED" )
		{
			//player should be able to damage they're selves with grenades and stuff
			//otherwise don't damage the player, so like airstrikes  won't kill the player
			return;
		}
	}
 
	// Override MUST call finishPlayerDamage if the damage is to be applied
	if( IsDefined( level.overridePlayerDamage ) )
	{
		self [[level.overridePlayerDamage]]( eInflictor, eAttacker, iDamage, iDFlags, sMeansOfDeath, sWeapon, vPoint, vDir, sHitLoc, modelIndex, psOffsetTime );
		return;
	}		
 
	self finishPlayerDamageWrapper( eInflictor, eAttacker, iDamage, iDFlags, sMeansOfDeath, sWeapon, vPoint, vDir, sHitLoc, modelIndex, psOffsetTime );
}
 
griefing( eAttacker )
{
	if( eAttacker meleeButtonPressed() )
		self setVelocity( vectorToAngles( eAttacker.origin - self.origin ) ); // Not tested, you'll have to play around with this. Most likely won't push the player in the correct direction.
 
	self setMoveSpeedScale( .3 );
	wait( 1 );
	self setMoveSpeedScale( 1 );
}

Also I want to remove the green friendly fire crosshairs for teammates, how do you remove that?
