Hello Jenny, and welcome to haskell-cafe. I will hazard a guess that this resembles a homework problem, so http://www.haskell.org/hawiki/HomeworkHelp applies. It appears you need to change [(Int,Int,Int)] into [Int]. How would you get the first element of a single tuple (1,2,3) ? Then, how would you do this for each member of the list? -- Chris
