Runs fine with package main but not package clock

I'm not sure where im going wrong here. The code runs fine in the workspace as well as my own Go set up on desktop but when i submit it here I keep getting errors. Ive solved the problem several different ways and each work in the separate environments. The issue is the number of arguments passed is not sufficient. I thought it was since time is using the struct correctly??

src/clock/clock.go 
package clock

import "fmt"

type Clock struct {
  Hours int
  Minutes int
}

// DEFINE A "Noon" FUNCTION HERE

func Noon (c Clock) {
  fmt.Println("Hours:",c.Hours,"Minutes:", c.Minutes)
}

func main (){
  time:= Clock{Hours:12, Minutes:0}
  Noon(time)
}

Forget it, im a dummy once again. It was much simpler than i thought it was. Take the function and pass it the struct. define the struct with new values, return those new values. I hate me...

You're working way too hard! Here's some hints:

  • you won't need to print anything
  • you won't need to import "fmt"
  • you don't need to create a "main" function
  • the "Noon" function doesn't need to take any argument(s)
  • but it does need to be declared as returning a "Clock"
  • the function will require a return, which passes back the "Clock" object

Hi Steve,

I figured it out shortly after posting this question (and pulling my hair out). I was definitely trying way too hard as the answer was so simple. Instead of mimicking the videos to try and understand, I needed to fully understand the concept of each of these modules and do what was being asked. From there the answer was easy.
