Table not filtering when selection made in another table

[Anonymous]

Hopefully this makes sense and someone can help me. So I have two tables in my model. The first (called parentDetails) is a list of parents names, their child's name, and what year group that child is in. The second (called surveyResults) are the results from a survey which also contains the parents names, this is how the two tables are linked - in a one to many relationship, the parent can only submit one response to the survey, but they might have multiple children at the school. 

My dashboard is very simple so far, I have a table which contains the count of each of the possible options from one of the questions from the survey, and a second table which lists all the year groups from the parentDetails table. When I select one of the responses, the list of year groups changes. When I select one of the year groups to filter the counts of the responses, nothing happens. Why is this? I need to be able to filter the responses to the survey questions based on which year group the parents child is in. but can't figure out what I am doing wrong.

I tried another route which might give better clarity about the problem. I created a Matrix, and from you can see below, a single value is repeated accross a row. When that option hasnt been selected by a parent for that year group, it correctly is left blank, but what I don't get is the unique values for each cell.

@Anonymous , how the tables are joined, In a single direction join filter will from 1 to many side.

If there two visual, slicer interaction can be off

I figured it out, I just needed to change the 'cross filter direction' option to 'both' in when editing the relationship between the two tables.

I was also missing the same. Thanks @Anonymous
