C # to VB.net conversion won't compile <param name = "x"

I cannot figure out how to convert this code from C # to VB.net. It says: no argument is specified for the 'y parameter in the calling code below.

Any suggestions?

thank

Calling CODE:

list.Sort(Utility.CompareContactListsBySortOrder) - error here in VB

      

        
        
        
      

    

CODE:

    /// <summary>
    /// Defines the compare criteria for two Contact List instances
    /// </summary>
    /// <param name="x">Contact List to be compared</param>
    /// <param name="y">Contact List to be compared</param>
    /// <returns></returns>
    public static int CompareContactListsBySortOrder(ContactList x, ContactList y)
    {
        if (x.SortOrder.HasValue && y.SortOrder.HasValue)
        {
            return x.SortOrder.Value.CompareTo(y.SortOrder.Value);
        }

        return 0;
    }
