[CrystalMethod]

Trying to make my NPC bypass the register system, but I'm getting two error codes when compiling and no amount of ****** has helped with this issue.
The error codes:

Код:

(96) : error 036: empty statement
(109) : error 029: invalid expression, assumed zero

The script with lines 96 and 106 highlighted:

Код:

public OnPlayerConnect(playerid)
{
	new query[126];
	
	format(query, sizeof(query), "SELECT * FROM users WHERE name = '%s'", GetName(playerid));
	mysql_query(query);
	mysql_store_result();
	if(!IsPlayerNPC(playerid));
	{
		if(mysql_num_rows() == 1)
		{
	    	SendClientMessage(playerid, -1, "That username is registered!");
			ShowPlayerDialog(playerid, DIALOG_LOGIN, DIALOG_STYLE_INPUT, "Login", "Please log in with your password.", "Login", "Close");

	    	SendClientMessage(playerid, -1, "That username is not registered. You may register it!");

    	    SetPlayerSkin(playerid, 101);
