[Scenario]

Basically, doing this:

pawn Код:

SetPVarInt(playerid, "Money", 100);

... is the same as doing this:

pawn Код:

PlayerInfo[playerid][pMoney] = 100;

So, you would basically need to change every line like this:

pawn Код:

PlayerInfo[playerid][pMoney]++;

to this:

pawn Код:

SetPVarInt(playerid, "Money", GetPVarInt(playerid, "Money")++);

So, your code...

pawn Код:

PlayerInfo[i][pCash] -= cost;

Could easily become:

pawn Код:

SetPVarInt(playerid, "Money", GetPVarInt(playerid, "Money") - cost);

NOTE: The variable names you use in PVars (i.e. "Money") are case sensitive. So, MONEY, is not equal to Money. I would recommend to make everything a CAPITAL variable, just to be on the safe side.
