This is a strange question. If cell B7 is like you say, then the answer to B5*B4*B3 will be seen in cell B7. D11 will therefore give you the answer B7*C7 which is the same answer as =(B5*B4*B3) * C7 . Why do you want to substitute the forumula into cell D11?

If you can explain why you are trying to do this, then it may help.
