Try this

=-C1

in cell D1
=C1*-1

I know this is a really bad work around, but how about :

(In D1) = (C1-C1-C1)

hey stefi
thanks...that worked, now how do i get rid of the "#value!" thats shows in
cell D1 if cell C1 has no value?

The following formula will display 0 if C1 is blank:

=-N(C1)

If you want to leave the cell blank then you should use the more
complex:

=IF(C1<>"",-C1,"")

Thanks a bunch...that worked.

=IF(C1="","",-C1)
The above will work if by "no value" you mean an empty text string, but if
you have other text you may have problems.
You could use =IF(ISNUMBER(C1),-C1,"") or
=IF(C1="","",IF(ISNUMBER(C1),-C1,"invalid input"))
