pawn Код:

GetDistanceBetweenPlayers(playerid, id)

Seems to me like this is the problem. Paste the function here and we can look at it.

Or, use something like this:

pawn Код:

IsPlayerInRangeOfPlayer(playerid, id, Float:range)
{
    new Float:pX, Float:pY, Float: pZ;
    GetPlayerPos(id, pX, pY, pZ);
    if(IsPlayerInRangeOfPoint(playerid, range, pX, pY, pZ))
        return 1;
    else
        return 0;
}
