JavaScript function deletes previously entered data

Question

Hello, I am using Adobe LiveCycle Designer version 9.0 and have created a one page form with a radio button list which allows a user to create an additional duplicate page when selected. All of the form was created as a master mage with the exception of the additional page radio button list that exists on "Page1." The script works great except all data entered by the user on Page1 is deleted when the additional page is created. Any suggestions would be greatly appreciated. I know just enough about JavaScript and FormCalc to paint myself into a corner (obviously) so speak slow and use small words please ...
Here is the code to add additional page:
topmostSubform.Page1.RadioButtonList::click - (JavaScript, client)
if (RadioButtonList.rawValue=="1")
{Page2.presence = "visible";}
else if (RadioButtonList.rawValue =="2")
{Page2.presence = "hidden";}
else
{Page2.presence = "hidden";}

I see two things that are problematic:
In general, you should try to avoid putting fields on a master page...you can sometimes experience unexpected results when you do.  Move your table to the body page instead and your problem will go away.
All of your fields are set with binding of "No data binding" (Object-->Binding-->Data Binding).  As a result, if you save your form, close and re-open it, the data will likely be lost.  At a minimum you should set the data binding to "Use Name".
Some other recommendations:
Try to avoid using so many rectangles...they are unneccessary, and the the number of objects used on your form can impact performance.  Use borders around text fields or text objects instead.
You should have a single table rather than two separate tables on two separate pages.  If you add a second page, then the totals at the bottom of each page will only reflect the totals for that page.  Create a dynamic table and allow people to add new rows rather than adding an entire page.  The use of a flowed layout and a content area on the master page will prevent the data from flowing into the footer and will force the creation of a new page as needed.
You have a bunch of scripts on your dropdowns that try to connect to a database connection that doesn't appear to exist.  Remove these if they aren't needed.
Because the Approving Official field is on the master page, it will appear at the bottom of every page.  Do you want it at the bottom of every page, or just at the bottom of the last page?  If the bottom of the last page, then add it to the body page in a flowed layout, or create two separate master pages.
Week Ending appears at the top of every page, but you have to enter a value on every page.  Set the data binding to "Use global data" and it will ensure that the values on each page are kept in synch.
