pawn Код:

GivePlayerMoney(playerid,random(20000));
GivePlayerMoney(userid,random(0-20000));

is bad, since it gives random money to the playerid, and another random to the userid.

pawn Код:

new randval = random(GetPlayerMoney(userid));
GivePlayerMoney(playerid, randval);
GivePlayerMoney(userid, -randval);
