First make sure that the Row1 in Table5 is set to Repeat in the Object > Binding palette. Your script looks good, but if the object is not set to repeat, then the script will fail silently.
If you have a look in the Custom Object Library, you will see a Page Navigation object. This is a collection of buttons (with script) that will allow the user to move between pages.
Another option to allow a user to access different parts of a form is to use an Index button. There is an example here: http://assure.ly/h4sIcQ.
If you put the top part of the form onto the Master Page, then it will be visible for all design pages.
Hope that helps,
