I'm stuck. Using Excel 2002, Win XP Pro

Here's a two-column data table and one column is where I enter a daily
number. The next column shows the difference between the present day and
the day before as a positive number.

Here's the file:
http://home.alltel.net/sayres5762/differencechart.xls

I'm using =IF(C80,C7-C8,"") to calculate the difference and display a
blank if there's no data.

The problem is when I must skip a day or two. I want to be able to leave
empty cells in Column C and have it not affect the Difference column or the
Total Difference. And if the Data entry is blank, I want the Difference to
display a blank, as well.

On the table enter a number.. say "80" on January 8 and you'll see what I
mean.

I've learned a few simple formulas but still have a way to go. Any help
would be appreciated.

Try this in D7, and copy down

=IF(C7="","",INDIRECT("C"&MAX(IF(C$6:C6<"",ROW(C$ 6:C6))))-C7)

which is an array formula, it should be committed with Ctrl-Shift-Enter, not
just Enter.

A quick and dirty solution: rather than an empty cell type in the same value
as the day above.
Format the cell to hide the data (in your case use yellow font) - this could
be done manually of with Conditional Formatting - select C7:C17 and use
"Cell formula is" with =C7=C6 and yellow font
best wishes
