When calling a rule and not passing the key’s of each parameter you are required to pass all the parameters. In the specific order, but if you pass the parameters with the keys your parameters will be optional. &lt;br /&gt;
And this is recommended because that way when upgrading a rule you can break some code accidentally. &lt;br /&gt;
&lt;br /&gt;
Hope this helps&lt;br /&gt;

This is an expression evaluation error coming from the rule mentioned there. You&amp;amp;#x27;re only passing one parameter to the rule instead of two, so the problem lies there.&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Related Action passing 1 parameter instead of 2</title><link>https://community.appian.com/thread/45639?ContentTypeID=1</link><pubDate>Tue, 23 May 2017 18:13:37 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:0dd5e6d7-5b75-4d4a-94f8-8e5b4d257a5f</guid><dc:creator>Colton Beck</dc:creator><description>Can you attach a screenshot of the referenced rule, as well as one of the related action configuration in the record?&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
