You see we cannot use a query rule directly to store value into a local variable or a rule input. You have to first use the query rule inside an expression rule and then use that expression rule to populate your rule input or local variable. This solved my problem. Thanks for your concern though.<div style="clear:both;"></div>https://community.appian.com/thread/8320?ContentTypeID=1Mon, 24 Mar 2014 08:37:16 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:4b5d0ee5-0e33-4908-a0cf-2f63c3e0f5b4Eduardo FuentesIs it related to your finding from <a href="https://forum.appian.com/suite/tempo/entry/e-104568">forum.appian.com/.../e-104568</a> ?<div style="clear:both;"></div>https://community.appian.com/thread/8319?ContentTypeID=1Mon, 24 Mar 2014 08:36:17 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:c1b6fee4-1228-4270-bdf0-ea068157fa15Eduardo FuentesMay I see the syntax of the whole expression when using the index() function?<div style="clear:both;"></div>https://community.appian.com/thread/8289?ContentTypeID=1Fri, 21 Mar 2014 19:08:32 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:c21b774f-6d9b-4b30-b69a-e50b967d1584aswinbI tried doing the index function but the error still exists if I try to use the same rule input which receives the value and try to store into it using savInto. Don&#39;t know why this is happening but usually everybody saves into the same variable that was used to recieve the value from the qurery rule.<div style="clear:both;"></div>https://community.appian.com/thread/8268?ContentTypeID=1Fri, 21 Mar 2014 03:31:25 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:98643dab-f6a6-4b5a-a4f2-43eea35f911eEduardo FuentesQuery rules return an array of items; even if there&#39;s only result the return type will be a list of items with a single item inside.<br /><br />If you are expecting a single value use the index() function to retrieve the first value of the query rule&#39;s array.<div style="clear:both;"></div>
