List matching based on key values

Lists-Logic
1

I am using Dynamo primarily to integrate external data into Revit. My external data source tables typically do not have the exact same data items as what I have in Revit, but always share a common key value. I was happy to find the “filter two lists by keys” node by @erfajo. Please see my first attempt at using this node and perhaps you might be able to tell why my filtered lists are coming back Null. I really appreciate your help!

Got it – thanks so much! Everything looks good and completes run, but parameters are not being written to Revit. Any thoughts? Thanks again!

Sorry, was rushing. I failed to convert the sorted element id list back to elements. All is good now - thanks again!
