Weekly Retention

[Anonymous]

Hi, I've implemented monthly retention using https://www.youtube.com/watch?v=vbg4Je1tuis Radacad recommendations and i am having trouble doing it on a weekly basis.

I changed it with weeknum as follows:

1) 

first order date (EOW) =

VAR Currentcustomer = entry_events[user_id]

return

CALCULATE(

WEEKNUM(MIN(entry_events[date]),2),

FILTER(

entry_events,

entry_events[user_id]=Currentcustomer

)

)

2) 

Weekly Customer retention % =

VAR CurrentWeekAfter =SELECTEDVALUE('WEEKS AFTER'[Value])

VAR CurrentFirstOrderWeek=SELECTEDVALUE(entry_events[first order date (EOW)])

RETURN

DIVIDE(

CALCULATE(

DISTINCTCOUNT(entry_events[user_id]),

FILTER(

entry_events,

WEEKNUM(entry_events[datetime],2)=WEEKNUM(CurrentFirstOrderWeek,CurrentWeekAfter)

)

),

DISTINCTCOUNT(entry_events[user_id])

)

3) 

WEEKS AFTER =

GENERATESERIES(1,10,1)

It says I have a mistake in second step as i guess :))) how should i correct it? any ideas?
