Using Range in Number Rule

[nogarth]

so running a rules like

      <ruleset name="Knights of the Old Republic: Commencement" rulesetmode="AND">
        <rule field="Volume" modifier="Is" value="2006" />
        <rule field="Series" modifier="Is" value="Star Wars: Knights Of The Old Republic" />
        <rule field="Publisher" modifier="Is" value="Dark Horse Comics" />
        <rule field="Number" modifier="Range" value="1||6" />
        <action field="Chronology Era" modifier="SetValue" value="02 The Old Republic" />
        <action field="Chronology Year" modifier="SetValue" value="BBY 3964" />
        <action field="StoryArc" modifier="SetValue" value="Knights of the Old Republic: Commencement" />
      </ruleset>

the Number range does not work it does not pick it up even if i change the 1||6 to 1,6 as shown in the original manual. Any suggestions.?
