bmiTell :: => Double -> String
bmiTell bmi
| bmi <= 18.5 = "You're underweight, you emo, you!"
| bmi <= 25.0 = "You're supposeldly normal. Pffft, I bet you're ugly!"
| bmi <= 30.0 = "You're fat! Lose some weight, fatty!"
| otherwise = "You are a whale, congratulations!"
This code got me an error, “parse error on input ‘=>'”
I have no idea why.
Any help?
