Hi,

I have been using functions in excel successfully before. All of sudden,
when i enter functions, excel does not show the calculated result, but rather
show the function itself. That is, if cell A1 is "abcde", in cell A2, i put
in =left(A1, 3). Cell A2 does not show "abc", but show "=left(A1, 3)"
literally. It is not just problem with left function, but every function. I
have tried ctrol+', but does not work.

I noticed that when i input the function in Cell B1, as soon as I start with
"=", the box that display "B1" on top will change to "sum" and grey out. I
wonder if this is something suspicious though.

Can anyone please help? Thanks.
