I'm not too clear on what you mean to say. You say you want to sum in 2
rows (40 & 41). This doesn't seem right.
Anyway I made some assumptions about what you want. The following 2
macros do something like what you are asking for. We may need to fine tune
this after you see it.
The first macro goes into the sheet module of the sheet that holds your
data. Right-click on the sheet tab, select View Code, and paste this macro
into the displayed module. This macro is triggered by any change to any
cell on the entire sheet. The code in the macro stops anything from
happening unless the changed cell is in Column F. It further stops action
unless the remainder of the equation (row number minus 39)/34 is zero.
If these conditions are met, the above macro calls the second macro.
The second macro goes into a regular module.
The second macro simply inserts 2 rows below the action or Target cell
row and places the active cell in Column A of the second of these two rows.
You could move the code in the second macro into the first macro and
then have only one macro. You would have to make some changes to the code
of the second macro if you did this. I chose to use the 2 macro construct
only because you might have some other things that you wanted to add to the
second macro.
You might have to change some of the numbers in these macros to get
exactly what you want. I'll send you a small file with these macros in
their proper places if you send me a valid email address for you. My email
address is . Remove the "nop" from this address. HTH

Hi,

I am a beginning user with very limited knowledge of macros. I am looking
to
add the following functionality. Presently I have a spreadsheet with
enough
room for 32 data input rows before I sum two columns' results (columns D&F
in
rows 40 and 41). Obviously, as time goes by, more rows will be needed for
additional input. I would like for the user to, upon pressing the enter
key
at the last cell of data input for that last data row entered, to have
excel
automatically insert a new row immediately below and move the cursor to
column A for new input. Is this possible without adding too much
complexity?

Thanks for all the assistance!!!
Pete
