I am quiet new to autoit and scripting itself.Kindly look at my code and suggest me a better way to do it.The following code works but when i try to get the form elements by name or type (for eg $fm.name=='email') it fails !!.Also i don't have much knowledge on dom elements ,kindly enlighten me on it related to my code.

objective:login to blogger account

my code

#include <ie.au3>
$oIE = _IECreate("https://accounts.google.com/ServiceLogin?service=blogger")
_IELoadWait($oIE)
$oForm = _IEFormGetObjByName ($oIE, "gaia_loginform")
$oFormElements = _IEFormElementGetCollection($oForm)
for $fm in $oFormElements
				 if($fm.type=='text') Then
						_IEFormElementSetValue($fm, "Found You", 0)
							 elseif($fm.type=='password') Then
										_IEFormElementSetValue($fm, "Found You", 0)
			  elseif($fm.type=='submit') Then
		  _IEFormSubmit($oForm)
	  endif
  
	 
  
   next
