how do i carry a balance to next row without it continuing down?

[Modine]

i have made a worksheet that adds and subtracts across the row, each row is a
month, then the balance in the last colunm jumps down to the next row
(month)first column. everything works great but i don't want the balance for
the next month continuing down to the each month same for the ending balance.
what i want is to have it end each time with just the beginning balance for
the coming month, then as i add a percentage rate it will add across the row
and put the ending balance in the next row (month)

i hope this make sense
