Word counter doesn't work

Hello, 
 
I tried using this javascript code on my forum: http://testforum.lithuanianforum.net/ , but it doesn't work. Any ideas?

Code:

$(function(){$(function(){

               var MinNumberOfChars = 50;
               var ico_compl = "http://i73.servimg.com/u/f73/18/10/89/49/ok-gre10.png";
               var ico_incompl = "http://i73.servimg.com/u/f73/18/10/89/49/exclam10.png";  
          
          if($("#text_editor_textarea").length != 0){
                  $("input[type='submit'][name='post']").attr("disabled", true).css("opacity", "0.5");      
                  $(".sceditor-container").after("<br/><div id='div_minchars' align='center'><div id='div_minchars_header'> Minimum characters to send a message: " + MinNumberOfChars + " </div><div id='div_minchars_info'></div></div>");
                  
                  var sceditor = $("#text_editor_textarea").sceditor("instance");                 
                  var str = sceditor.val().replace(/ |\n|\s+|\[img\].*?\[\/img\]|\[.*?\]|\[\/.*?\]|:.*?:/gi,'');
                  var str_len = str.length;
                  
                  if(str_len >= MinNumberOfChars) $("input[type='submit'][name='post']").attr("disabled", false).css("opacity", "1");
                  
                  sceditor.keyUp(function(e) {
                     str = sceditor.val().replace(/ |\n|\s+|\[img\].*?\[\/img\]|\[.*?\]|\[\/.*?\]|:.*?:/gi,'');
                     str_len = str.length;
                     if(str_len >= MinNumberOfChars) {
                        $("#div_minchars_info").html("You've written <span style='color:green'>" + str_len + "</span> character(s). You can now send the message <img src='" + ico_compl  + "' />");  
                    $("input[type='submit'][name='post']").attr("disabled", false).css("opacity", "1");
                     }else{
                        $("#div_minchars_info").html("You've written <span style='color:red'>" + str_len + "</span> character(s). You need " + (MinNumberOfChars - str_len) + " character(s) to send this message <img src='" + ico_incompl  + "' />");
                        $("input[type='submit'][name='post']").attr("disabled", true).css("opacity", "0.5");
                     }
                  });
               }
            })});

Try this one: Click.

It's in progress in my forum and works fine. It counts words and chars and appears below the editor.

Hello @Vitavili,
I just test your code on my testing forum and it seems working fine



have you set your javascript In the topics?

darki, thanks for the code, but the problem was that I set it on all pages not in the topics. Thanks @Black-Shadow !
