You're trying to apply 'take n' to a value of type 'a' ('take n' requires [a]), moreover putting the value of 'take n s' into the FString further constrains its type to be [Char] == String.

First of all, thanks a lot for your reply. I thought that in this case my type a was String ( which I know is [Char] ) since I give fInit a value of type g ( FString n _ ) and a value of type a ( s ) and I return a value of type g ( FString n (take n s) ) David
