I know this is an easy one for you wizzes, but it escapes me at the moment
and I never seem to have the right terminology to look up what I am trying to
do.

I have two columns of data (A, B) and a third that is the result of a
calculation of A & B
(A*B=C). I need column C to become static data rather than the formula as
columns A & B will eventually be removed.

I know it's simple - sorry and thanks!
