How to select Item from Lookup page

Hi to all,

I have add a new page Action in P 31: Item List (picture 1).

When I call Action it is open a new page like picture 2.


I want when I select Item No from picture 2, to be selected in P: Item List.

Here is code that I have in Action in P 31:"Item List"

IF PAGE.RUNMODAL(50005,ItemAttributesFilters)=ACTION::LookupOK THEN
BEGIN
Item.GET(ItemAttributesFilters."Item No.");
// CurrPage.GETRECORD(Item);
// CurrPage.SETRECORD(Item);

CurrPage.SETSELECTIONFILTER(Item);
CurrPage.UPDATE;
END;

I try with, GETRECORD,SETRECORD,SETSELECTIONFILTER but still it doesen't work
I use NAV 2016.

Any advice,
Thanks a lot,
