Column: Calculate the DateAdd function against a Min value in the column

[vsslasd1]

I have a formula: 

FirstDate = DATEVALUE(CALCULATE(Min('tablevalues'[Period]),FILTER('tablevalues','tablevalues'[Period]<>"Current")))

And that works correctly.

I would like to subtract 7 days from the result of the above.

But I am getting an error using this function: 

FirstDateMinus7=DATEADD(DATEVALUE(CALCULATE(Min('tablevalues'[Period]),FILTER('tablevalues','tablevalues'[Period]<>"Current"))),-7,DAY)

@vsslasd1 , you can simply subract 7

FirstDateMinus7= DATEVALUE(CALCULATE(Min('tablevalues'[Period]),FILTER('tablevalues','tablevalues'[Period]<>"Current"))) -7
