It works in VSC :/

When I run my code in Visual Studio Code terminal it works fine. I have

package main

import ( "fmt" )

func HalfPriceSale(prices map[string]float64) map[string]float64 { products := map[string]float64{"OCKOPROG": 89.99, "ALBOÖMME": 129.99, "TRAALLÅ": 49.99} for product, price := range products { products[product] = price / 2 }
return products }

func main() {
fmt.Println(HalfPriceSale(map[string]float64{"OCKOPROG": 89.99, "ALBOÖMME": 129.99, "TRAALLÅ": 49.99})) }

I get:

$ go run main.go map[OCKOPROG:44.995 ALBOÖMME:64.995 TRAALLÅ:24.995]

src/sales/sales.go
package sales

func HalfPriceSale(prices map[string]float64) map[string]float64 {
  products := map[string]float64{"OCKOPROG": 89.99, "ALBOÖMME": 129.99, "TRAALLÅ": 49.99}
  for product, price := range products {
    products[product] = price / 2
    }  
    return products
}

But in the challenge I get the error: Bummer! Expected HalfPriceSale(map[OCKOPROG:89.99 ALBOOMME:129.99 TRAALLA:49.99])["ALBOOMME"] to be 64.995 but got: 0.000 instead.

The function needs to use the argument passed in as the source of the data to process instead of hard-coded literal data. The challenge passes in different arguments to validate the function.

Otherwise your code is good and you can actually pass by just changing the first line to:

  products := prices

Took me a minute, but I see now! Thank you Steven!
