Script crashes after 10-14 loops

[BrianTheLibrarian]

Hello I am having a bit of trouble with the following script. It runs fine for 10-14ish loops and then it crashes with the following error message.

Quote

$tags=$oIE.document.GetElementsByTagName($tagName)
$tags=$oIE.document^ERROR
Error: The requested action with this object has failed.

Here is the chunk of code that seems to be giving me problems, any suggestions would be greatly appreciated.

While $count < $iRows
    $y = 0
   _IENavigate($oIE, $url[$count])
   _IELoadWait($oIE, 500);


   $colLinks = _IELinkGetCollection($oIE)
   For $oLink In $colLinks
      If $oLink.className = "Title" Then
         $oFound = $oLink
         _IEAction ($oFound, "click")
         ExitLoop
      EndIf
   Next
   _IELoadWait($oIE);


   GetData("h1", "Title")
   GetData("a", "Name")
   GetData("span", "Score1")
   GetData("span", "Value1")

   $tags = $oIE.document.GetElementsByTagName("div")
   For $tag in $tags
      $class_value = $tag.className

      If $class_value = "left" Then
         $bookInfo[0][$y] = $tag.innerText
         $y = $y+1
      EndIf

      If $class_value = "right" Then
         $bookInfo[0][$y] = $tag.innerText
         $y = $y+1
      EndIf
   Next

   $cell = "V"&$startRow

   _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $bookInfo, $cell)
   _Excel_BookSave($oWorkbook)
   $count = $count+1

 WEnd

Func GetData($tagName, $classVal)
   $tags = $oIE.document.GetElementsByTagName($tagName)
   For $tag in $tags
       $class_value = $tag.className
       If $class_value = $classVal Then
         $bookInfo[0][$y] = $tag.innerText
         $y = $y+1
         ExitLoop
        EndIf

   Next
EndFunc

Few questions:

AutoIt version you are using ?
Windows version NAME + 32 or 64 Bit ?
IE version ?

btw.

Turn on the _IE errorhandler.  There are some situations where the dom isn't loaded, or in a state that can't be queried.

It's a bug with the functions...edit: oh, you are referencing the dom directly...definitely turn on the error handler.

You can read about using COM Error Handler with IE.au3    here:   How to use IE.au3  UDF with  AutoIt v3.3.14.x  

EDIT:

You can try this workaround:

Local $oDocument = $oIE.document
If Not @error Then
    $tags = $oDocument.GetElementsByTagName("div")
    ....
EndIf
