        {
            SendClientMessage(playerid, COLOR_GREY, "You are not near a buyable business.");
        }
    }
    return 1;
}

Line/code that causing the warning: PlayerInfo[playerid][pCash] -BizInfo[idx][bPrice];

The effect is .. no deduction on player money when he buys the biz

Simple change

pawn Код:

PlayerInfo[playerid][pCash] -BizInfo[idx][bPrice];

to

pawn Код:

PlayerInfo[playerid][pCash]=-BizInfo[idx][bPrice];

Hmm... I have my concerns about this answer. I thought he was trying to do "deduct BizInfo[idx][bPrice] from PlayerInfo[playerid][pCash]". Your solution does this: "Set PlayerInfo[playerid][pCash] to be the opposite of BizInfo[idx][bPrice]".

-= deducts
=- makes it the opposite

(For those who didn't understand, let's say x = 5 and y = 7)
x -= y is the same as x = x-y and the answer is -2
x =- y is the same as x = -y and the answer is -7 (the opposite of y)
