[Calisthenics]

The mistake is in this line:

pawn Код:

if (strcmp(BizInfo[i][bOwner], pName(playerid), false) == 0) return SendClientMessage(playerid, 0xDC143CAA, "ERROR: You Already own this business");

If player is not on biz icon to buy it, "i" will be -255 and there is no checking before the line I mentioned. So you need to move this line:

pawn Код:

if(i == -255) return SendClientMessage(playerid,-1,"ERROR: You need to be on biz icon to bought it");

on top and be like this:

pawn Код:

new i = GetBizID(playerid);
if(i == -255) return SendClientMessage(playerid,-1,"ERROR: You need to be on biz icon to bought it");
if (strcmp(BizInfo[i][bOwner], pName(playerid), false) == 0) return SendClientMessage(playerid, 0xDC143CAA, "ERROR: You Already own this business");
