pawn Код:

SetPVarInt(playerid, "tries", GetPVarInt(playerid, "tries") + 1);

Or you can use the function AddPVarInt

pawn Код:

AddPVarInt(playerid, "tries", 1);

Then you need this:

pawn Код:

stock AddPVarInt(playerid, varname[], int_value)
{
    SetPVarInt(playerid, varname, GetPVarInt(playerid, varname) + int_value);
}
