So i have got this.....

pawn Code:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if (newkeys & KEY_FIRE)
{
    if(IsPlayerInRangeOfPoint(playerid, 3.0, 1554.5713,-1675.6034,16.1953))
    {
        SetPlayerPos(playerid, 246.4274,107.8742,1003.2188);
        SetPlayerInterior(playerid, 10);
    }

But when i put C instead of "KEY_FIRE" it tells me i need to define C


How would i do that


Please Help Me Please
