[Haskell-cafe] Newbie list question

[junkywunky]

type Person = (NI, Age, Balance)
type Bank = [Person]

credit :: Bank -> [Person]
credit [(a,b,c)] = [(a,b,c)]

This code works when I type in:

credit [(1,2,3)]

but doesn't work when I type in:

credit [(1,2,3),(4,5,6)]

Any help?

Thanks in advance.
