I think Lockwelle's original idea was to have 2 formula fields in the report footer. One formula in the left column and one in the right column. Each formula would check if the number should be printed in that column. If so, return the number. If not, return nothing.
It looks like you are using CNT as a counter. The logic for the left column in the report footer would look something like
If (cnt should be printed in the left column) then totext(cnt,0,"") else "".
You will need the corresponding formula for the right column also. The thing you have to figure out is how to decide if cnt should go in the right column or the left.
Hope this helps.
