There you can do

pawn Код:

//
    if(strcmp("/repair", cmdtext, true) == 0) {
        if(gTeam[playerid] == TEAM_STUNTS) {
            if(IsPlayerInAnyVehicle(playerid)) {
                RepairVehicle(GetPlayerVehicleID(playerid));
                SendClientMessage(playerid, COLOR_GREEN, "Your vehicle has been repaired!");
            } else {
                SendClientMessage(playerid, COLOR_GREEN, "You must be in a vehicle!");
            }
        } else {
                SendClientMessage(playerid, COLOR_GREEN, "You must be on the stunter team!");
        }
        return true;
    }

But thats gets confusing if you got a large block of code between

pawn Код:

//
    if(strcmp("/repair", cmdtext, true) == 0) {
        if(gTeam[playerid] != TEAM_STUNTS) { // if the player is not in TEAM_SUNTS
            return SendClientMessage(playerid, COLOR_GREEN, "You must be on the stunter team!");
        }
        if(!IsPlayerInAnyVehicle(playerid)) { // not in the vehicle
            return SendClientMessage(playerid, COLOR_GREEN, "You must be in a vehicle!");
        }
        RepairVehicle(GetPlayerVehicleID(playerid));
        return SendClientMessage(playerid, COLOR_GREEN, "Your vehicle has been repaired!");
    }

No else if needed since we return always, you can also leave the brackets away if you only got one line after the if statment

pawn Код:

//
    if(strcmp("/repair", cmdtext, true) == 0) {
        if(gTeam[playerid] != TEAM_STUNTS)
            return SendClientMessage(playerid, COLOR_GREEN, "You must be on the stunter team!");
        if(!IsPlayerInAnyVehicle(playerid))
            return SendClientMessage(playerid, COLOR_GREEN, "You must be in a vehicle!");

        RepairVehicle(GetPlayerVehicleID(playerid));
        return SendClientMessage(playerid, COLOR_GREEN, "Your vehicle has been repaired!");
    }
