|The Excel #Ref! error means there is an unknown reference or address in a cell formula. |
There are times where you want to copy and paste cells (ctrl+c) vs. cutting and paste(ctrl+x). One problem with cutting is that you can create #REF! to an existing formula.
To see this, enter into:
A1 the number 1
Cut A3 and paste to A1
A2 = #REF!
Instead Copy A3 and paste to A1.
