Help calculating the total weight lost from starting weight D1

I would like to figure out how to calculate total weight lost (or gained) from the starting weight in cell D1. The new weight will only be entered every other row. Then I plan to add, in cell F1, total weight lost. The results would be displayed in cell F2.

Here is the attached copy of the workbook. I can do most of the simple sum formulas but I am having issues with calculating every other weight to the total cell located to the right.

Thanks,

Hi try this in G1
=$D$1-INDEX($D$3:$D$62,LARGE(IF(($B$3:$B$62<>"")*($D$3:$D$62<>""),ROW($D$3:$D$62)-ROW($D$3)+1,""),1))
after copying the formula use ctrl+Shift+Enter but not just enter

Punnam,

This did not work, it returns a #value! error. The only values of concern are the weights in the D column, the issue is doing the calculations regardless of the blank cells. I appreciate your quick response. It's a bit late tonight, will respond in the morning.

Or, if I've interpreted correctly, this non-array formula in F3 and copied down:

This non-array formula will work as well.
