not without a macro.As an alternative you can have a "manual input cell"
somewhere else,say a25,and in a 24 have =if(A25="",vlookup(c15,d25:e25,2),a25)
..

I have setup a formular for a cell A24. This cell have the formular of
vlookup(c15,d25:e25,2). This returns the correct results in A24. My problem
is this:

I woulld like to be able to change the results in A24. Let say the resulet
in A24 is $500.00. I change A24 to $775. When I do this I loose the
originial vllok formulatr in A24. I have protected the sheet but then it
will not let me change the results in A24. Is there anyway to lock the
formular but change the results of A24 manually?
