Sum Unique Rows after Unpivot

I have a table with unique rows. I had to unpivot the table based on a column to get a value I was looking for. The problem is, after I unpivot the table, all of the other measures I would try to make get blown out of proportion because of the unpivot.

Basically, I need to sum the values of a column BEFORE the unpivot. But, I still need to do the unpivot.

Any ideas??
