I need some help automating a row insert from one sheet to a second sheet. I
think a macro is needed, but I'm not sure how to set one up as I've never
worked with them, nor do I know how to program it. I'd appreciate a little
help setting up the macro.

Basically, I retrieve my stock quotes into the Quote sheet, and it updates a
total amount. I want to archive the current date and amount to a Database
sheet. But there is an important twist. If there is already a row inserted
in the Database sheet with the same date, then I only want to update the
amount, not insert another row. Once the current date changes, then it is
okay to insert another row.

This is my data. Sheet Quote has the total amount. The amount is dynamic
and will change whenever my stock quotes update the prices of the securities.
Stock Price Amount
IBM $91.45 15000
MSFT $29.48 20000
------ -------- -------
Total 35000

Sheet Database stores the current date and current balance on the last row,
as well as archived dates and balances going back in time. Only the last row
with the current date is to be updated. The data is sorted in ascending date
as you can see.
Date Amount
11/24/06 30000
11/25/06 33000
11/26/06 34000
11/27/06 35000 ** This row can be updated multiple times
or a new row inserted below if date changes
