I have an excel spreadsheet with several columns. To verify that data has
been entered correctly I have a column that adds all the columns and should
equal zero if they are entered correctly. Since the "proofing column" is not
always visable unless I tab to the end of the worksheet, I would like to hear
a beep if the column is greater than zero to signal that I need to check my
entries. It would be great if I could see a dialogue box that would tell me
my entries are not correct.

Thanks,
