Create dynamic label for Customer based on page filter

Hi all, 

I've a model with the following entities:

• Customer DIM, including customer acquisition date
• Sales Fact, with all the purchases made by the Customers
• Calendar DIM, that is linked to Sales Fact.

On the Customer DIM (which is not directly join to Calendar) I created a dynamic column reporting the year of acquisition for each customer: Year of acquisition = YEAR(CUSTOMERS[CREATION_DATE].[Date])

In the report page I put a filter object allowing to select the Year from the Calendar. I configured the filter for only allowing single item selection.

What I want to do is to calculate dynamically on Customer level a label telling me about the state of the Customer in that year: New Customer (if the Customer was created in that year) or Existing. I would like to use the filter to compare sales made by New and Old Customers. Of course, the same Customer could have a different label based on the applied filters. 

I tried creating a measure like this for giving me the selected year: 

Selected year = IF(HASONEVALUE(CALENDAR[YEAR]);VALUES(CALENDAR[YEAR]);YEAR(TODAY()))

and tried to create a measure in the Customer DIM like this:
