On the Foreign Income Diagnostics Form, T2209, (Form below is just an example off the internet, ignore the red box and arrow that isnt my info) I have columns A, B and C filled out. Column D is empty. When it totals up though, it populates ``Deduction according to`` column instead of ``Carry the result to line`` column. How do I correct that If column D is empty, there should be no total in Deduction according to subsection total.
