Try using this one. This one should work with your script. I can't see an error there, Try pasting an error code so I can see it.

Code:

	if(strcmp(cmd, "/fine", true) == 0)
	{
	    if(IsPlayerConnected(playerid))
	    {
			tmp = strtok(cmdtext, idx);
			if(!strlen(tmp))
			{
				SendClientMessage(playerid, COLOR_GRAD2, "USAGE: /fine [playerid/PartOfName] [money] <reason>");
				return 1;
			}
			new playa;
			new money;
			playa = ReturnUser(tmp);
			tmp = strtok(cmdtext, idx);
			money = strval(tmp);
			if (PlayerInfo[playerid][pAdmin] >= 2)
			{
			    if(IsPlayerConnected(playa))
			    {
			        if(playa != INVALID_PLAYER_ID)
			        {
				        GetPlayerName(playa, giveplayer, sizeof(giveplayer));
