Go to page buttons in a Master Page

I have a number of multi page forms where I would like to include the following buttons in the header on the Master page. I have two Master pages one for page 1 and the second one for all remaining pages. It looks like this:

Ignore the blue lines, please, they are guides in the master page. Notice the arrowhead buttons on the right side. I've used the following scripts to make the buttons work. I used a very small textfield as the focus point at the top of each page now on the Master Page 2:

Double Left arrow heads button has this script: xfa.host.setFocus(form1.page1.TextField1);

Single left arrow head button has this script: xfa.host.pageUp();

Single right arrow head button has this script: xfa.host.pageDown();

Double right arrow heads button has this script: xfa.host.setFocus (form1.page5.TextField1); I edit this button depending on the last page in the form.

Before I put this at the top of each page. Then I decided to put the buttons (and the whole header) on Master Page 2 (saves time and formatting each page). All buttons work fine except the right double arrow head (go to last page). I understand why it's not working, but I don't know how to fix it. I'd welcome any help available.

Thanks,
