Replace Above Expression

I use above to display the previous data in the custom table. I have a trouble that Above Function doesnt work when I wanna show the Total of Month, Quarter , Week in the following picture:

can anyone help me? please... and another problem, the column 'Prog Year N -1' is % change compare to last year. ( explain : in the row 'July' will show the % change compare to July of last year ).

Thank in advance!
