I have a custom content type
Topic, another custom content type
Sub-Topic, and a taxonomy
Topic Tags. I'd like to be able to display the sub-topics on the page for each topic that has any of the same topic tags.
I'm using panels to define how pages look topics, and I was trying to use a view for the sub-topics. I can make a view that filters by a specific tag, but I can't figure out how to pass the tags that the topic node has to the sub-topic view.
