Week to Date Sales

Hi, I am trying to display week to date sales on the card visualization. I do have a date table and have columns verifying the number of the day of the week (Sunday =0, Monday = 1, etc). I even created Start of the Week and End of the Week calcualted columns.

I've seen quite a few topics on how to achieve this, but nothing is working. I can get the totals if I use a Table, but I just want to capture that WTD number on a card and it update everyday without a filter applies. Any help would be appreciated. Thanks!
