You don;t have Dates?
If you have dates then you would not need WEEK DATES. Unless you are going to make Week1 (which consists of 7 dates), Week2 (7dates) Week 3(7Dates) and so on....
What are you trying to achieve with the week dates?
You can maybe use
WeekStart(Date)as WKS
WeekEnd(Date) as WKE
To get start and end dates for the weeks and if you click on Week 1 it will select respective start and end dates from above fields.
And you'll have a Date Field which will give you all dates from that week.
