pawn Код:

if(GetPlayerClan(playerid) == 1)

This is because the function GetPlayerClan(playerid) is not a boolean, its rather a integer; but not sure as you haven't provided the code related PlayerInfo[playerid][pClan].

If its a boolean var, then here:

pawn Код:

stock bool:GetPlayerClan(playerid)
{
    return PlayerInfo[playerid][pClan];
}
