Cascading Drop down issues in Excel

Hello I've never built a cascading dropdown from scratch.  I have a template that I use every time I need to create one.

Please use the attachment as guidance

Question 1 - On the Tracking Worksheet tab, when select DMI in Area, Column E only gives the selection of Reporting and Reporting when it should be Reporting and Soup.  (selecting TCS in column C does it correctly)

Question 2 - Why when you select an Activity List on the Tracking WorkSheet tab, all the selections on Column I on the Service_Activity List tab are displayed?

Is it all in the order or is there a way to do a cascading dropdown where it works as intended?

Example, On the Tracking Worksheet  tab When you select DMI then Reporting is the only selection and then there's only 3 selections in column I Activity

I have a work around but it requires putting (DMI) at the end of Column B on the Service or Deliverable and (DMI) at the end of every activity that's selected for the Area DMI (same exercise for (TCS), (GR), (SS)

Question 3, this is a nice to have, but it might require coding, If you make all the proper selections, and then go back and change G, is there a validation that tell you Column H and I are incorrect?

From what I can see your Data validation formula uses Match, which will only return one item

I have added a data validation method that works for you.

It works on Named Ranges linked to a Data Validation list using the INDIRECT unction. When an area is selected the relevant range is used by the Data Validation.

Check it out and I'll add a fuller explanation if it's what you want

In reply to your PM I have looked at this again. You mention the possibility of 87 choices so I have added a way to allow the same named range to apply to multiple selections in the Data Validation Lists. Check the example and reply here as to whether this is what you mean.

When the selection is made in the Area Column of the Tracking sheet then the relevant choices are made available in the Data Validation lists. This is done using two Dynamic Named Ranges, AdvancedFilter and some VBA.
