Incorrect structure was found in the PDF message

Question

I have a folder level javascript that creates a custom menu item which when clicked inserts a page at the end of the open document.
Sometimes when executed, a dialog box appears that says "An incorrect structure was found in the PDF file" but the page is inserted anyway.
We work with a lot of documents that have been scanned as a PDF. However, as I said it only occurs with some documents....
Is it just the way they have been scanned? Or is there an error in my script? Or perhaps another explanation?
Could I suppress that particular alert since the page is inserted anyway?
---edit----
I have just checked the script with Acrobat 7.0 and although I don't get the 'Incorrect structure was found in the PDF' message the javascript debugger appears with this message in the console:'Exception in line 19 of function anonymous, script folder-level:App:InsertSummaryPage.js' but once again the page is still inserted anyway.
Here is the javascript I am using to insert a page:
trustedNewDoc = app.trustedFunction(function ()
app.beginPriv(); // Explicitly raise privilege
this.insertPages({nPage:this.numPages-1, cPath:"/C/Program Files/Adobe/Acrobat 7.0/Acrobat/Javascripts/SummaryPage.pdf"});
app.endPriv();
app.addMenuItem({cName:"Insert Summary Page", cParent:"Tools", cExec:"trustedNewDoc()"});
Thanks

Larry – I did what you said and got the form to comply. I combined all the pages and suffered as the software bombed about every third or fourth move I made. For some reason, the form fields work like they should, but the text never goes into the order you want it to. I was having to move the text to the bottom and it would bomb every time I did. I would launch the software again and it would work for about 5 or 6 moves, but every time I moved the text to its proper place in the order, it bombs the program.
But your suggestion was the correct one.
I did get the message that some of the names were the same and I’ve had that happen before. I’ve gotten better at my naming convention. I’m hooked up to a network here and some times when they are doing whatever they do behind the scenes, I’ve had the software not cooperate or not perform optimally.
Our forms here were all built long ago, and the nature of them is to cram as much info onto a page as you can. It’s not uncommon to have 150 – 200 items per page. This makes compliance a real effort.
Thanks again for all your help.
