Change that line to:
new nxtlevel = PlayerInfo[playerid][pLevel]+1;
It happened because MAX_PLAYERS is equal to 500. And you created this variable with 500 cells(or whatever u can call it). So the id of those cells are 0,1,2,....499. And there is no cell called 500 so when u tried to get the 500th cell, which does not exist, you got this error.
