Weekstart and multiple years in Combo Chart problem when comparing weeks

[#1]

Hi all,

I have a problem in the presentation of the data in a combochart.

The combochart looks like this:

current year data in bars

previous year in a line

the data is grouped per week (weeknumber)

Eveyrthing looks fine, except that when I use this formula in the dimension tab

=dual(WeekStart([Date]), Week(Date))

It shows the first Monday of every week of the previous year.

I would like to see the first Monday of every week of the CURRENT year.

I've attached the (sample) application.

Best regards,

Arjan
