My problem is three-fold. First I can only use my number pad in excel.  If I
use the numbers below the function keys on my keyboard, excel will not format
them (currency, accounting etc.). Second, when I use my kep pad and type in a
decimal point, it appears as a little square instead of a period/decimal
point.  Third, while reasearching how to fix this problem, I discovered that
when I click on Options under the tools menu, I can only access the view tab.
When I try to click on other tabs I get this message "Your entry cannot be
used. An interger or decimal number may be required."  I have tried detect
and repair and reintalling excel with no success  I would appreciate any
help.
