Sum of the total when selecting slicer date

Hello,

I ran into a brick wall and I am stuck. So my end goal is trying get the sum total of the "Totals" row from selecting the dates from the slicer. I am not sure if I am explaining this right but I made an example of it. Is it even possible? What I tried to do is =SUMIFS(Table1[Pieces Loaded],Table1[Week of Month],Slicer_Week_of_Month,Table1[Month],Slicer_Month)

It did not work =( please help. Thanks
