[Haskell-beginners] Functions in "where" block.

Hello everyone, I can't figure out why the following function does not work: myFun :: Integer -> Integer myFun x = op x + ep x where op x = 99 ep x = 1 -- squawks here Yeah it's a stupid function, but I was just trying to declare two functions in the "where" block. I expected this to work and always return 100. This is the error I get while compiling: ================== Prelude> :l fun.hs [1 of 1] Compiling Main ( fun.hs, interpreted ) fun.hs:4:15: parse error on input `=' Failed, modules loaded: none. ================== Could someone please tell me where I am going wrong? Thanks in advance. Regards, Venu Chakravorty.
