The "i" specifier signifies a required parameter, thus it does not accept a default value.
To allow a default value you should use the optional equivalent (capitalized ("I")).

So your code would be:

pawn Код:

if(sscanf(params,"I(500000)I(250000)S(For Sale)[128]",cost,payout,name))return SendClientMessage(playerid, 0xFF0000AA, "Usage: /createbiz [cost] [payout] [name]");
