It's possible that you were getting an 'array out of bounds' error from this command, causing it to not function properly. Install the crashdetect plugin for future reference on these sorts of strange occurrences. pID was probably an INVALID_PLAYER_ID (65535) or because you were using an array size of [7] for 'money' for some reason... if the player's ID was greater than 6, it would have also crashed the command/server when you tried to access 'money[playerid]'.
