_IETableGetCollection on page that needs to be navigated to

I'm trying to get table data from a webpage that needs to be navigated to. I am currently using _IECreate to create an IE object, then using some more code to login to the site. After login is confirmed, I need to navigate to another page and get table data from it. 

My code looks like this:

$oIE = _IECreate("url")
 
; run login script
 
_IENavigate($oIE,"https://.....tablepage")
 
$oTable = _IETableGetCollection($oIE)
 
ConsoleWrite("oTable = " & $oTable & @CRLF)
ConsoleWrite("oTable error = " & @ERROR)

The object $oTable appears to be empty, and an object type error is returned.

The messages written into the console are:
