1,809 Pointstotal declared and not used
I've just started go, and I think I've used total properly. It might need to be capitalized to be exported to another file. I've also tried removing sales in the 2nd file. No luck. Any help would be greatly appreciated, like a small hint, thanks!
package sales
func main () {
var total = 1234.56
}
package main
import(
"fmt"
"code.my.com/git/sales"
)
func main() {
fmt.Println(sales.total)
}

So just change the "t" in "total" to a capital "T" in both files and you should pass the challenge.

Treehouse TeacherYou can take what Steven Parker said above rather literally. If you declare total within a function, then its scope is limited to that function and it needs to be used within that function. total was declared as a package-level variable in the starting code for the challenge, and it needs to remain a package-level variable. (You might want to click Restart to reset the code to its initial state.)
The problem is that total isn't exported from the sales package. To do that, you simply need to capitalize its name.

231,248 PointsDid you change it in both places (one in each file/tab)? And change only the names, don't add any additional code!
