Locally this works without issues however the interpreter is complaining that the value of hours is not incrementing and I'm not sure why.
This is what I have locally to test
package main
import (
"fmt"
)
type Hours int
func (h *Hours) Increment() Hours {
return (*h + 1) % 24
}
func main() {
hour := Hours(6)
hourIncramented := hour.Increment()
fmt.Println(hourIncramented)
}
This is from the treehouse editor.
package clock
type Hours int
func (h *Hours) Increment() Hours {
return (*h + 1) % 24
}

"Locally this works without issues" because you're still expecting a return value from the function and using it. But that's a different test criteria than the challenge requirements, which say to *"Convert Increment to ... modify the receiver directly".
So for the challenge you have a few conversion steps to do yet:
- the instructions said to "modify the value at that pointer" — you still need to modify the original value
- your new return won't need a value
- your function declaration must be changed to reflect that there is no longer an Hours being returned

*h=(*h + 1) % 24

your function declaration must be changed to reflect that there is no longer an Hours being returned-- Keep in mind, there is nothing to be returned if pointer values are being updated, you'll need to remove the Hours return value.your new return won't need a value-- Removed return value due to pointer modification of (h)the instructions said to "modify the value at that pointer" — you still need to modify the original value-- Changed declarations to pointer values so it doesn't copy a new (watch 4:40 - end of the video for an example)
