How do I convert an existing MS Excel worksheet tracking a simple.

I am a novie Excel user who has tracked the activity of my simple savings
account with an Excel worksheet. I would like to set up this existing
worksheet to perform autosum functions when I enter deposits, withdrawals,
and interest instead of manually doing the math on a calculator to arrive at
the balance total after each entry.

Enter the following formula in the cell below your data; (it assumes your data is in column b, from row 2 to row 5:

=SUM(B2:B5)

Hope this helps,
