You're using it in a loop, that loops through all players, then defines them as "i", therefore you should use "i", not "playerid".
Also, as you can see in the function title:

pawn Код:

stock sscanf(string[], format[], {Float,_}:...)

There's no "playerid" parameter, so you cannot use it, but in this case you should use "i" anyways.
