Get the count of a value using the weekYear

[asalamun]

I'm using WeekYear as a dimension, but I am trying to calculate the count of records that have a DateInitiated prior to WeekYear dimension value. So for weekYear being 1-2017 I need the count of everything initiated prior to that date

here is what I am trying now, but nothing is coming up.

=count(distinct {<DateInitiated={'<WeekYear'}>} RecordID)

Thank you

Perhaps this?

=count(distinct {<DateInitiated={$('<' & =Max(WeekYear)-1)}>} RecordID)

OR

=count(distinct {<DateInitiated={"<$(=Max(WeekYear)-1)}>} RecordID)

The first gave me a zero value, and the second one just gave an error

Will you able to provide sample?
