At Last statement in a loop

Hi all,

My program is doing sum kind of summation suring at last statement.

I want to sum for every row where stufe = 1 but the at last only sum for row 4 ( row 4 + row 5 values).

Why at last is not summing for row 1 ? (row 1 + row 2 + row 3 )

Row 1 value not summed. Its 0.
