This problem started when I was upgraded to Excel 2003.

When I receive an unprotected Excel spreadsheet from someone else, I am
unable to add a formula that works. For example, I will enter a sum
formula for a column of numbers, and the total will be 0.

I've tried:
* changing the the format of the input cells - back and forth - from text
to numerical, etc.
* turning on and off error correction, and sharing.
* copy, paste special, values.
* saving the worksheet under a new name.
* turning manual calculation on, and off, etc.
* Unchecking link external values under tools, options.

But the only thing that works is if I manually reenter each number in the
column, which defeats the purpose of a spreadsheet.

This is very frustrating.

Sounds like your column of numbers is formatted as text. On another column,
you can add 0 to each number to convert them to a real number. For example,
if your original numbers are in column A, you can enter the formula =A1+0
into the B1 cell and copy down. Then all the values in column should be
numbers and you can use the SUM function off of column B.

Maybe the numbers were imported from the web and contain the nbsp character
(ASCII code 0160).

Try this:

Select the range of numbers

From the Excel main menu:
<edit<replace
Find what: hold down the [alt] key....type 0160...release the [alt] key
Replace with: (leave this blank)
Click the [replace all] button

Does that help?

This sounds like a cell formatting issue. Your numbers are entered as text.
Simply changing the cell format won't change the contents. Thus, why it only
works when you manually re-enter the data.

Here's something you can try.

Enter the number 1 into any blank cell.
Copy that cell.
Highlight your range of data to convert.
Paste Special and select "Multiply"
Click OK
Delete the 1 that you entered originally.

This multiplies all of your data by 1. Anything Excel can recognize as a
number will be converted to a number without changing the value.
