Description

The variable specified by the “name” attribute in the <assign> tag should be declared in a <var> tag first.

Example

<?xml version="1.0"?>
<vxml version="2.0">
<form>
<!-- test_var is declared here -->
<var name="test_var"/>
<block>
<!-- test_var must be declared before assigning it a value -->
<assign name="test_var" expr="1234"/>
</block>
<block>
<prompt>
The test variable is set to <value expr="test_var"/>.
</prompt>
</block>
</form>
</vxml>

The output of the above script would be:
