How do I link many cells to one particular cell?

[Guest]

I am trying to link multiple cells to one particular cell and can't seem to
do it. I want the multiple cells not just to have the same information but
be connected to the same cell. I want multiple cells to take the information
from ex. cell D4. So everytime i change cell D4 every cell that is linked to
it changes. Do I have to input =D4 into every single cell that I want to
link or is there an easy way to mass link?

enter =$D$4 in one cell and copy it to the rest. The $ keeps the address
from changing relatively.

Are the cells on the same worksheet?

If yes, you could select all the cells that should get that formula and type
this:

=$d$4
but hit control enter to populate all the cells in the selection.
(the $'s keep excel from adjusting the address for each cell)

If D4 can be empty, you may want a formula like:

=if($d$4="","",$d$4)

(If d4 is empty, then =d4 will return a 0.)
