Most recent date using input date variable

[Anonymous]

Hi,

I have an app that wishes to present comparison data of two dates (present and a selected date in the past). The user can select the date which is then recorded as vInputDate. I now need to work out the logic to display the correct data line.

A simplified dataset would be:

Project Name	Data entry date	Data
Project A	01/08/2017	1234
Project A	01/09/2017	4123
Project A	01/10/2017	3412
Project B	01/08/2017	ABCD
Project B	01/09/2017	BCDA
Project B	01/10/2017	CDAB

So if the user selected 10/09/2017, the (fully working) app should display Project A: 4123 and Project B: BCDA, however with my current code (below) it also shows results for 01/08/2017.

=if([Data entry date]<=vInputDate,[Data])

Any advice on how I could execute this would be much appreciated.

Thanks

May be with Set analysis

Only({<[Data entry date] = {$(=Date(vInputDate, 'DD/MM/YYYY'))}>}Data)

what about

=if(fabs(vInputDate-[Data entry date])=fabs(min(vInputDate-[Data entry date])),[Data])
