Re: [Haskell-cafe] Please help from a newby

type Pkg = (Pkgtype,Address,Payload) type Table = [(Address,Port)]

update_table1::Table -> Pkg -> Table update_table1 [] (t,d,y) = [(t,d,y)]

The problem is that your function's type signature says it's returning a Table, which is a [(Address,Port)], but it's actually returning a [(Pkgtype,Address,Payload)]
