I have this formula in a column of cells: =+$H3-@Sum(I3:AB3)

Now the entire column of cells has the number which is underlined and when I
point to that cell the following statement appears:

mail to =+$H3-@Sum(I3:AB3) - click once to follow. Click and hold to select
this cell.

How do I get rid of the mail to deal with these cells?

Confused in Virginia. Thanks for the help.
