Excel XP Windows XP
In the past when I entered a number,say 15, and pressed
return, it showed a 15  Now it shows a 1.50  I have gone
into "Edit Cell" but the only relevant thing I can alter
there is the number of decimal places.  I have also looked
at "options" but to no avail.  I would ad this is in
worksheets that I had initially formated and it was
working.

Anyone got any ideas as to what I need to do to rectify
the problem
