Flipped sign issue for formula row and formula column intersection cell in oracle EPM Form

Hi,

I created on form using Forms 2.0 on Oracle EPBCS. The form has formula column at the end for the variance between the last two columns, and the form contains also formula row for the totals. Everything is fine and and totals row shows proper values and the same for variance column. The only problem for the intersection cell for the variance column and totals row. it always shows the proper amount, but in flipped sign. is that an issue with EPM Forms?or how can that be fixed?

Thanks,

Taha
