# Don't laught at me please; how to make Excel know last cell with info

Posted by Veronica P. on January 28, 2001 11:49 PM

Please do not make fun of me; my project is simple, even silly but I ran into an Excel problem that I can not solve and I find it kind of difficult to explain. I have column A and B as a simple way to update and reconcile my bank checkbook. In column A after the 2nd entry (which is a number-begining balance)
I have a formula that will add the prev bal with next entry of money (+ or -). I want instead to use the simple addition formula (which will give me the balance even when I have no more entries), to use something like this: if cell Bx is empty BUT not the LAST cell in range B1:B50 with an amount then add cell Ax+0 (zero) (because I get error otherwise) and if Bx is empty but the last one with amount, I want the result to be "", empty cell.
I use the range A1:B50; I have the formulas starting from A3 to A50; I need to get a result from that formula only when there is an amount in column B, and to get
"" in column A when B is empty.
A1 Balance B1 deposits/withdrawls
A2 2000 B2 300
A3 =IF(B2="",A2+0,A2+B2) B3 -200
A4 =IF(B3="",A3+0,A3+B3) B4 300
A5 =IF(B4="",A4+0,A4+B4) B5 empty
A6 =IF(B5="",A5+0,A5+B5) B6 200

Any help greatly appreciate. Thank you in advance.

Hi Veronica

Wouldn't dream of laughing, It's perfectly valid question.

Try placing this formula in cell A2 and copy it down as far as needed. It will give you a running total in Column A

=IF(B2=COUNTA(B2:\$B\$5000)=1,A1,IF(OR(COUNTA(B2:\$B\$5000)=0,B2=""),"",SUM(\$B\$2:B2)))

The absoluting with the Dollar signs is important.

While this maybe a way to get a running total Excel does offer more efficient ways via means of Data>Subtotals and Pivot Tables. Give them a go sometime.

Hope this helps
Dave
