How do I filter a list so that only the length of select elements are returned?

Once I get my elements filtered down to the desired Info the Length parameter is coming back empty… please help!

Only the instances have a Length–you are currently trying to get the length of the element’s Type. Are you trying to get the length of only a single instance of each column type?

Yes, there are only 6 different col types, and only 4 different lengths (once rounded) and I can’t get the lists to sync up.

Something like this?

Still returns empty. I’m baffled. Thanks for your help.

Oops, I was accidentally covering up one of the wires. Hopefully this is a bit clearer:

It should be associating each element’s instance to a family type. Therefore, the Dictionary.ValueAtKey will return instances rather than types.

Thank you so much. I have been banging my head on this for days. Apparently I really need to read up on Keys. Thanks Again.
