Notify area in NT screen OMRON

I set Control Area L0000 and Notify Area L0010 in my PT.

I wrote the code as on the picture. I think that first MOV should write number of current screen to the DM12 but it is still #0000 even the displaying screen is ie. #3.
another MOV works OK and the screen is switching to the #9.

What am I doing wrong?

Thanks

I attached picture but it seems unvisible
So, the code looks:

-I 0.07 I-------I MOV L10 DM12I
I
I-I MOV #9 L00 I

You need to either map the system words in the PT in setup to some DM area in the PLC or stick a macro on each page that writes the system word for screen number to a DM in the PLC

rory: Your advice is for an NS screen, not a NT screen.

pszczepan: Is the NT screen an NT30 or NT31? It makes a difference.
