Why does my Scala enumeration not work?

I have the following Enumeration

class Market extends Enumeration {

  type Market = Value
  val A开发者_StackOverflow中文版SX = Value("ASX")
  val LSE = Value("LSE")

}

In the same package but a different class I'm trying

if (Market.ASX = ...)

And I am getting a compile error not found: value Market

It should be an object.

object Market extends Enumeration {
  type Market = Value
  val ASX = Value("ASX")
  val LSE = Value("LSE")    
}
