Cascading dropdowns where secondary columns match

Posted on by 634

I'm not really sure how to word the question but here is what I have. 

 

  • Two dropdowns. One for Medium and one for Medium Details
  • Medium has a primary column named Medium Name which contains values such as Banner, Video, Text Link, etc....
  • Medium has a secondary column named Medium Detail Type which contains values such as img, vid, lnk
  • Medium Details has a primary column named Medium Detail Name with values such as img-1, img-2, img-3,vid-1, vid-2, vid-3, lnk-1, lnk-2, lnk-3

Initially, I was trying to make the Medium Details dropdown dependent on Medium by using a formula like this which worked when I was using comboboxes:

 

Filter('Medium Details', Medium_CB.Selected.crfeb_mediumdetailtype in crfeb_mediumdetail)

 

Besides this not working I didn't think it was efficient. Since then I added to the Medium Details data source a column for Medium Detail Type.

 

What I am looking to do now is return the Medium Detail Name  where both Medium Detail Type  from both data source match. I've a number of searches and tried a number of solutions but I'm just not landing on the right one. Most of the cascading tutorials out there are not comparing secondary columns.

    That would be one of the videos I watched. Note that his data source situation is not anything like mine. That's why I couldn't get his solution to work.
