How can I check to see if a token is unset before setting it; essentially using the same link to set/unset a token?

[toutla]

I am trying to use the same drilldown link to toggle the function of setting and unsetting the same token.  

Current Code

<drilldown>
   <condition>
      <set token="arrangements_details">true</set>
    </condition>
</drilldown>

The idea - just need correct syntax

<drilldown>
   <condition match="$arrangements_details$=null">
      <set token="arrangements_details">true</set>
    </condition>

   <condition match="$arrangements_details$=true">
      <unset token="arrangements_details">true</unset>
    </condition>
</drilldown>

Any suggestions?

I'm guessing this is about using dependent panels. There are a couple of problems in your match statement

1. Using = null - use isnull()

2. = true must be quoted with &quot;

See this

<dashboard>
  <label>Click Toggle</label>
  <row>
    <panel>
      <table>
        <search>
          <query>
            index=_internal earliest=-5s
            | stats count by _time
          </query>
        </search>
        <drilldown>
          <condition match="isnull($arrangements_details$)">
            <set token="arrangements_details">true</set>
          </condition>
          <condition match="$arrangements_details$=&quot;true&quot;">
            <unset token="arrangements_details">true</unset>
          </condition>
        </drilldown>
      </table>
    </panel>
    <panel depends="$arrangements_details$">
      <table>
        <title>arrangements_details=$arrangements_details$</title>
        <search>
          <query>
            | makeresults
            | eval Drilldown="Clicked"
            | table Drilldown
          </query>
        </search>
      </table>
    </panel>
  </row>
</dashboard>

Hope this helps
