I have a search that is returning one row, and this has multiple fields on it, A, B, C, and D.
Field C I use for display in a <single>
It appears I can't use $row.A$ in a <drilldown>? How do I access this field for sending it to the next dashboard?
Hmm, per http://docs.splunk.com/Documentation/Splunk/latest/Viz/PanelreferenceforSimplifiedXML#single_.28even... it does seem like $row.___$ should be available - I'll keep investigating.
