This script is meant to assign a variable (a) using menu script and then pass that var and login info using form id="login>. It does not pass (a) correctly. Am I missing something?

code:

 
<vxml version="2.1" xmlns="http://www.w3.org/2001/vxml">
  <property name="inputmodes" value="dtmf"/>
  <var name = "a" />
  <menu id="menu1" dtmf="true">
      <prompt> Press 1 to xxxx. Press 2 to xxxxx. Press 3 to xxx.</prompt>
<choice next="#choice1">1</choice>
<choice next="#choice2">2</choice>
<choice next="#choice3">3</choice>
  </menu>
  <form id="choice2">
    <assign expr = "3" name = "a" />
    <block><goto next="#login"/></block>
  </form>
  <form id="choice3">
    <assign expr = "4" name = "a" />
    <block><goto next="#login"/></block>
  </form>
  <form id="login">
    <field name="id" type="number">
           <prompt>Please enter your user eye dee followed by the pound key</prompt>
    </field>
    <field name="pin" type="digits?minlength=7;maxlength=7">
           <prompt>Please enter your pin</prompt>
           <filled>
              <submit next="http://www.tojo931.com/gmaps/voicexml.php" namelist="id pin a"/>
          </filled>
    </field>
  </form>
</vxml>

Yes. You must assign a value to "a" within the <block> tags. Since <assign> is not a legal child of the form tag, the assignment is not happening properly.

Depending on the tool/environment that you are using, you can usually validate your code before running to make sure its correct.

You should also check the platform logs -- this script should throw an "error.semantic" that you should be able to see fairly easily.

Hope this helps.
