Hi, can I get some help on this question .. I'm stuck

Fix the error in the below code so that it will run and print the string "Hello, world!".

package sales

import ( “fmt” “ math”

       var total = 1234.56

func main() { report.go(total)
fmt.Println(report.go) }

hello.go 
package sales

import (
           “fmt”
           “math”

           var total = 1234.56

func main() {
           report.go(total)  
           fmt.Println(report.go)
}

First looking your code I see a missing " ) " closing your imports.

When you use "var" you need to declare the type of the variable: Ex:

var score float = 1234.56

or you can declare and initialize using inference type: Ex:

score := 1234.56

Hope this could help.

The code shown above doesn't seem at all related to the challenge linked by the button and mentioned on the first line.

The issue in the "Hello, World!" challenge is that a variable is assigned but never used. But there's a perfect place to use it on the next line, and it saves repeating the same string again.

If you have an issue with the code shown above, it might be a good idea to create a new question for it.
