Use slicer selection in a function

[clachi80]

I have created two slicers both listing all hours in a day populated from two tables with one column

The user must select one hour in each slicer: one indicating the starting hour and one the ending hour

Based on the selection I should be able to calculate the number of hours between the two selections and finally use this value in the following function that is reported in a column of a different table. 

MidDaysSecDiff =

IF (

FORMAT ( WorkHour[FirstMail], "Short Date" )

<> FORMAT ( WorkHour[LastMail], "Short Date" ),

3600 * 10

* (

CALCULATE (

DISTINCTCOUNT ( 'Calendar'[Date] ),

FILTER (

'Calendar',

'Calendar'[Date] > WorkHour[FirstDayEndTime]

&& 'Calendar'[Date] < WorkHour[LastDayStartTime]

&& 'Calendar'[WorkDay] = TRUE ()

)

)

- 1

),

0

)

(the difference between the two selected hours will replace the number "10" in "3600*10"

I have tried using DATEDIFF(SELECTEDVALUE(StartSlicer), SELECTEDVALUE(EndSlicer), HOUR) without success

I have also tried to create a new measure that returns the difference of the two values or create a variable but I am not able to retrieve that value in the above function

Could you please tell if and how can I get the desired value in the function?

You could make two What If Parameters from 1-24 (hours); see the Modeling tab.  That will make two new tables and add slicers to the report.  There will also be measures created to harvest the selected values.  You can then add a variable to your measure that calculates the difference between those two whatif measures.

If this works for you, please mark it as solution.  Kudos are appreciated too.  Please let me know if not.

I've also created two tables through the What if parameter and added a measure with a variable that returns the time difference between the two hours selected in the two slicers... and it worked, I'm able to see the correct value on a card

My problem is that I don't know how (and if possible) to use this value in a function in a computed column like the one indicated in my post. How can I use my VAR in this function instead of the number 10?
