Excel 2010

Suppose I have the formula =Degree(A1) in cell B1.

In cell C1 I write a formula using the formula in B1 as one of the
parameters.

I think I understand how to name the formula in B1. Chooseing Ctrl + F3 seems to do the trick. But when I try to auto-fill my formula in C1 down
the column it doesn't seem to work correctly.

Any help appreciated.
