Question:Is it too long or fractional?

I've had a solution, which had many terms like this
(a d + c a m + a d c+ ................................................................................................................
...................................................................................d m )/( a d+ c + ...............................
....................................... c m)
I then wanted to define the lengthy fractional solution as function f by copying the soltion and pasting it behind "> f:= ".  It looked like this:
>f:=
 (a d + c a m + a d c+ ................................................................................................................
...................................................................................d m )/( a d+ c + ...............................
....................................... c m)
 
Then I encountered two things that really puzzled me.  First, the program didn’t allow me to place  “;” at the end of the lengthy expression, therefore I was not able to define it as function f.  I thought I might have a better chance if I worked it in a new worksheet.  So I copied the expression to a new worksheet. But every time the old worksheet where the expression was located appeared in the new worksheet, instead of the expression only that I intended to copy.  I’d appreciate it greatly if someone out there could explain to me what was going on, especially how I could define the lengthy expression. Thanks in advance.
