[Google Wave APIs] No container specified Problem

[FX-VISION]

Hello,

I have a Problem with the Wave Gadget API.
I have a HTML Formular and every time I submit,
It says: No container specified 404 Error.

What went wrong with my code:

<?xml version="1.0" encoding="UTF-8" ?>
<Module>
<ModulePrefs title="LastFM" height="280">
  <Require feature="wave" />

</ModulePrefs>
<Content type="html">
<![CDATA[
<center>
<script language="JavaScript">
text = ""
var text = parseInt(wave.getState().get('text', '0'));

function init() {
      if (wave && wave.isInWaveContainer()) {
        wave.setStateCallback(stateUpdated);
      }}

function stateUpdated() {
if(!wave.getState().get('text')) {

      }
      else { if(text!=wave.getState().get('text');){
        wave.getState().get('text');
document.write(text);}

function serch() {

 a = document.formular;
track = a.track.value
artist = a.artist.value
track = track.replace(/ /gi,"+")
artist = artist.replace(/ /gi,"+")
var text= "<center><form name='formular' onsubmit='serch
();'>Track:<input type='text'  name='track'>Artist:<input type='text'
name='artist'><input type='submit' value=' go! '></form><br>"

;
wave.getState().submitDelta({'text': text});

document.write(text);
}
</script>
<form name='formular' onsubmit='serch();'>Track:<input type='text'

type='submit' value=' go! '></form>
</center>
]]>
</Content>
</Module>


I hope you can help me.
