TList cannot be invoked

    If CountList(K_E_HighScoreList) > 10
    	For Local purge = 11 To CountList(K_E_HighScoreList)
    	      Local purgee:THighScore = THighScore(K_E_HighScoreList(purge))
    	Next
    End If

I'm trying to grab specific types in a list by their indexed number.
The error is coming from this line:

Local purgee:THighScore = THighScore(K_E_HighScoreList(purge))

Any ideas?
