Hello, I'm creating a voicexml appliacation.

I want to store an user input into a global variable.

I wondered, the input should be stored in the fieldvar. shouldn't it? After I tried it with this, i tried to store it in an global variable:

<assign name="myvar" expr="'myinput'"/>

but somehow it didn't work. I used value expr="var" as expr.

<var name="myProdukt" />


<form id="test">

<field name="var">
<prompt bargein="true" bargeintype="hotword" >Sagen Sie ein Produkt</prompt>

<grammar root="main" version="1.0" xml:lang="de-DE">

  <rule id="main" scope="public">
    <one-of>
      <item> p1 </item>
      <item> p2 </item>
      <item> p3 </item>
      <item> p4   </item>
    </one-of>
  </rule>

</grammar>



<filled>
<assign name="myProdukt" expr="<value expr="var"/>"/>
</filled>

</field>


</form>

<<!--[...] Here i want to use the input.-->

</vxml>
