Only the skins who should have the password need the array PasswordClass[..] before the function AddPlayerClass. Not all skins!

Also you should write OnPlayerRequestClass like this:

PHP код:

public OnPlayerRequestClass(playerid,classid)
{
    for(new i;i<sizeof(PasswordClass);i++)
    {
        if(classid == PasswordClass[i])
        {
            ShowPlayerDialog(playerid,DIALOG_SKINPW,DIALOG_STYLE_INPUT,"Password","Put in the password for the skin","Next","");
            return 1;
        }
    }
    ShowPlayerDialog(playerid,-1,DIALOG_STYLE_INPUT," "," "," "," ");
    return 1;
} 


So when you choose a skin who needn't a password the dialog will hide.
