pawn Код:

CMD:free(playerid, params[])
{
    new id, amount, szDialogString[250];
    if(sscanf(params, "ui", id, amount)) return SCM(playerid, -1, "Syntax: /free [playerid] [price]");

add this after ^^^^ or just uncomment it

pawn Код:

if(price>4500)return SCM(playerid,-1,"Error: Price cant be above 4500");
if(GetPlayerMoney(id)<price)return SCM(playerid,-1,"Error: player doesnt have enough cash");

it checks if the target player doesnt have enough and if so give an error message in this case if player have less than the amount requested by the cop
ang the request amount of the cop limited to 4500..
