External Grammar tweak

[support]

There's no fix for this in the grammar file. Before assigning your digits to a variable, you'll have to use Javascript to remove the spaces. For example:

Code: Select all

<form>
  <field name="digits">
    <!-- Your external grammar -->
    <prompt>Your prompt</prompt>

    <filled>
       <assign name="digits_without_spaces" expr="digits.replace(/ /g, '')"/>
    </filled>
  </field>
</form>

The Javascript inside the expr attribute takes the input from the "digits" field and replaces all spaces with empty strings.
