[Solved]decrease knife damage

is there a code to decrease the ammount of damage the knife does to a player?

_callbacksetup.gsc:
[php]CodeCallback_PlayerDamage(eInflictor, eAttacker, iDamage, iDFlags, sMeansOfDeath, sWeapon, vPoint, vDir, sHitLoc, timeOffset)
{
self endon("disconnect");
if(sWeapon == "knife_mp")
iDamage = 20; //20 HP lost from a knife
[[level.callbackPlayerDamage]](eInflictor, eAttacker, iDamage, iDFlags, sMeansOfDeath, sWeapon, vPoint, vDir, sHitLoc, timeOffset);
}[/php]
