GPS debugging problem

[L Dries <bertus.dries@planet.nl>]

I have the following procedure that I a busy with degugging. I am 
working in GPS. I want to see the value of Grid(X, Y).x_val and 
Grid(X,Y).y_val
The problem in GPS is that I cannot set that element only the parameter 
Grid which is not recognized as an record, possibly because it is 
declared in another package.

    procedure On_OK(Object : access Gtk_Button_Record'Class) is
       pragma Unreferenced (Object);
       n_ch : integer;
    begin
       n_ch := choices(integer(Get_Active(Fill_Dialog.StrN_Combo)));
       Grid(X, Y).Fill := n_ch;
       Grid(X, Y).Status := manual;
       Set_Impossible(Grid(X, Y).x_val, Grid(X, Y).y_val);
       Make;
       On_Dialog_End(null);
    end On_OK;

What to do to see those values
