Selecting Minimum Selected date in variable

[RizwanAfzal]

I am trying to get minimum of selected date range in a variable but not getting. My Filter selection field is Churned Date and variable definition is like 

=Min(GetFieldSelections(Churned_Date))

[TcnCunha_M]

=Min(Churned_Date)

you don't need  get selections

[TcnCunha_M]

=Min(Churned_Date)

you don't need  get selections
