I would say copy the current values of A1 to a helper column...say G then
enter this formula in A1 =IF(C1="X",B1,G1).

If you want, you can keep the column G hidden.

I have a worksheet that I want to try and eliminate manual activity. To
simplify the question, assume I have three cells A1,B1 and C1. If the
value
in C1 is X then I want to place the value of B1 in A1. If the value in C1
is
not X I want to leave the value in A1 alone.

I am trying to create a worksheet with YTD values and I want to place the
appropriate values in the appropriate month's columns. I don't want to
change the other values for other month's that have already been
colleceted
and stored. It looks like I have a loop if I am trying to "pull"
information
in A1. I can't figure out how to "push" information from another cell
into
A1 without being in A1. Hope this makes sense.
