Call to undefined method

[Simplyput]

I have a script that I am trying to add some hacks. At the moment I am trying to add a new function for users to delete movies. However I keep getting this Call to undefined method error message on line 97.

Here is the class and where I am having the issue.

<?php

class K_System

	var $membership;

var $isplayer;

var $player= FALSE;

var $mod = FALSE;

var $id;

var $ext;

var $actionset = FALSE;

var $action;

var $dual = FALSE;

var $message;

var $delete_movie;


function K_System()
{

	if (is_player())
	{
		$res = $db->sql_query("SELECT is_player, is_mod FROM ".$prefix."_K_account WHERE userid = '".$userinfo['user_id']."'");
		list($is_player, $is_mod) = $db->sql_fetchrow($res);

		# Player check
		if ($is_player == 1)
		{
			$this->player = TRUE;
		}

		# Mod check
		if ($is_mod == 1)
		{
			$this->mod = TRUE;
		}

		if (($is_player == 1) && ($is_mod == 1))
		{
			$this->dual = TRUE;
		}

	}


	$ismod = FALSE;

	if (isset($_GET['id']))
	{

Here is the delete function.

function delete_movie()

  $row33 = $db->sql_fetchrow($mmov);

I have been working on this for the last two weeks and still lost. Where am I going wrong with this? Any help will be greatly appreciative. I know its something simple but just not seeing it.

Maybe something like this will help?

    function view()
    {

    $this->loadExt($this->ext);

    $ext = new $this->ext;

    if ($this->actionset)
    {
		if(empty($this->action)) {
			throw new Exception("Action is not set");
		}
		if(method_exists($this, $this->action) == false) {
			$methods = get_class_methods($this);
			$error = "No such method '".$this->action."'\nAvailable methods:".print_r($methods,1);
			throw new Exception($error);
		}
        $extension->{$this->action}();
    }
    else
    {
        $ext->showPage();
    }

}

Then if you get the second exception, check if that the method name is exactly correct.

I think you have a syntax error in the line following OpenTable(). This renders the method invalid and non existent.
