Count Duplicates that appear in other sources within one table

Hello,

 

I am wanting to count the duplicate ids which appear within other tables contained within my model.

So within table 1 (List 1) I want to add columns for each list I have 1-9 etc.

If so within List 1 (table) I will have a new column called list 2 which will count how many times the id within the row in list 1 appears in list 2. I will have this for each list.

All tables have a column called Id in which the id is could be shown more than once.

 

Ideally I want to do this without using a relationship between these tables, an inderect relationship is fine.

 

Thanks in advance

@jaltoft Not sure I specifically understand. You should be able to do something like:

COUNTROWS(FILTER('Table2',[table2ID] = [ID]))

Sorry, having trouble following, can you post sample data as text and expected output?

1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.
