Challenge with Date Range in Set Analysis

[Anonymous]

I've been trying all day to implement what I thought would be a simple date range in a set analysis example. I have a data island for Date selection. The selection will be used to summarize the previous 90 days of sales.

Example (not working):

sum({$<[_Date]={">=($(=SelectDate)-90) <=$(=SelectDate)"} >} NetSales)

I have been able to get it working by hard-coding the lower value:

sum({$<[_Date]={">=04/01/2018 <=$(=SelectDate)"} >} NetSales)

I'm sure my problem is simple and I'm not seeing it. Appreciate the assistance.

Perhaps something like this?

sum({$<[_Date]={">=$(=Date($(SelectDate)-90)) <=$(=SelectDate)"} >} NetSales)

Try this

=sum({$<[_Date]={">=$(=Date(SelectDate - 90,'DD/MM/YYYY'))<=$(=SelectDate)"} >} NetSales)

Thanks Manish but this ends up filtering out ALL records resulting in $0.

This one worked! Thanks William!
