[Haskell-beginners] Parse error: naked expression at top level

[Roelof Wobben]

Oke, 

So  In the file I have to load I must put the first 2 lines.
And in the prompt I have to do the last line,

Or is there a way I can use all three lines in a file ?

That last line is fine at a GHCi prompt but not in a program.  (Files loaded by ghci are not scripts!  They are treated the same way as program files fed to ghc or runhaskell.)
