First, insure you are running this from SciTe and include the messages generated during the program run when you ask for help like this.

Second, you need to understand that a Window Title and a Document Title are not the same thing. The document title is controlled by the <TITLE> tag in a document. An IE Window Title typically is a Document Title with a fixed string appended - like "- Microsoft Internet Explorer". _IEAttach offers a "windowtitle" mode in addition to the default "title" mode.

Again, please study the messages that that IE.au3 generates to the SciTe console -- a lot of work went into making them helpful.

This is a particularly ugly way to attach to IE:

$window = WinGetTitle("")
$len =  StringTrimRight($window, 30)
$oIE = _IEAttach($len)

$sTexts = _IEBodyReadHTML($oIE)

You might be trying to do _IEBodyReadHTML() before the DOM is ready. Throw in an _IELoadWait():

$window = WinGetTitle("")
$len =  StringTrimRight($window, 30)
$oIE = _IEAttach($len)

_IELoadWait($oIE)
$sTexts = _IEBodyReadHTML($oIE)
