Qliksense variable from Calendar

[amiroh81]

I developed models in the past using Qlikview and recently switched to Sense.
One of the things I used a lot was selecting a date from a calendar and embedding the selected date into a variable.
I tried to use the Date picker option but I couldn't embed the date into my variable.
Does anyone have experience in a similar case and can explain to me what I should do?
I would like to make the selection of the date before running the model.
Thanks

create a variable by using expression like 

GetFieldSelections(date)

in date picker include date field as 'date'

Thanks for the idea,
Help me partially.
My problem is that I want to select the dates before I refresh the model and I would like to have the option of choosing the last days when opening the model.

When I insert the DATE value I am actually limiting the Calendar view to only the last date loaded in the model.

Thanks
