a) remember it is zero-based.

So firstChild is the same as childNodes[0]

b) "You would have to adjust all the relative references"

There are other references in the piece that are not expecting that additional icon.

Thank you Dave,
 
I am a bit further now. But still have some 
trouble.
 
Now I have :
the make pages icon, then the interface icon, the 
interface icon contains an entry frame, and the protopage. So I addes only an 
entry frame.
 
I made 3 pages with the template
 
 
I changed the code in the makepagesicon into: 

 
icon.nextSibling.childNodes[2].duplicate(templateData.presentation[0].page.length 
- 1);
 
icon.nextSibling.attributes.title = 
templateData.presentation[0].name;
 
//set the page titles
for (i = 0; i < 
templateData.presentation[0].page.length; i++){
  
icon.nextSibling.childNodes[i].attributes.title = 
templateData.presentation[0].page[i].name;
}
 
 
If I preview the presentation and I got only one 
page: Page 2. It contains the right text and picture but there should be 3 
pages.
 
Then  I changed 
icon.nextSibling.childNodes[2].duplicate(templateData.presentation[0].page.length 
- 1); 
into 
icon.nextSibling.childNodes[1].duplicate(templateData.presentation[0].page.length 
- 1);
 
Then with previewing I got 3 pages,  it doesn't show page 1, then 
it shows page 2 and 3 (with correct pictures and text) and then it shows a page 
undefined.
 
I should think icon.nextSibling.childNodes[2] is the 
protoPage? But why doesn't that work? and why do I get some result 
with icon.nextSibling.childNodes[1]? And why I 
don't get page 1 then?

You have to be very careful around 
  template architecture.

You see the script icon above the Interface icon 
  called makePages?
Open it up and look at the first line of 
  code.

icon.nextSibling.firstChild.duplicate(templateData.presentation[0].page.length 
  - 1);

That is making the pages of your presentation:

icon = 
  here, this icon
nextSibling = next icon downward
firstChild = next icon 
  rightward
duplicate = duplicate

So it is saying, duplicate the 
  protoPage icon x number of times.

When you insert your entry pane on to 
  the Interface page, you have inserted a sibling between makePages and the 
  target, protoPage.
So the relative logic is destroyed and the piece is not 
  being built.

You would have to adjust all the relative references in 
  the piece to take into account the added entrypane 
  icon.

  Hi, I am very new in Xerte.
  I am trying to understand the simple presentation 
  template.
  I would like to ad an entry frame to 
  the interface icon and then add som cusom buttons.
  However, when I insert an entry frame, 
   the application doesn't work correctly anymore. The text icon shows 
  'undefined' and I cannot go through the pages.
  What I am doing wrong?
   
  Thanks for any help
  Patricia
