AutoIT | Click On A Div Button | Browser

I have been trying to click on a specific button on a website. I have finally concluded to ask for help here.

This my whole program:

#include <ButtonConstants.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#include <ie.au3>
#include <MsgBoxConstants.au3>
#include <GuiEdit.au3>
#Region ### START Koda GUI section ### Form=
$Form1 = GUICreate("KingDomLikes Bot", 334, 150, 192, 124)
$Group1 = GUICtrlCreateGroup("Login", 0, 0, 137, 145)
$username = GUICtrlCreateInput("Username", 8, 32, 121, 21)
$password = GUICtrlCreateInput("Password", 8, 64, 121, 21)
$Login1 = GUICtrlCreateButton("Login", 8, 96, 123, 25)
GUICtrlCreateGroup("", -99, -99, 1, 1)
$Group2 = GUICtrlCreateGroup("", 144, 0, 185, 145)
$repeat = GUICtrlCreateInput("0", 152, 32, 121, 21)
$Label1 = GUICtrlCreateLabel("Loop", 152, 16, 28, 17)
$start = GUICtrlCreateButton("Start", 152, 64, 163, 73)
GUICtrlCreateGroup("", -99, -99, 1, 1)
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###
logintosite()

Func logintosite()
While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit

         Case $Login1
            Global $oIE = _IECreate("http://addmefast.com/")

            $username1 = GUICtrlRead($username)
            $password1 = GUICtrlRead($password)

            $emailform = _IEGetObjByName($oIE, "email")
            $usernameform = _IEGetObjByName($oIE, "password")
            $buttonweb = _IEGetObjByName($oIE, "login_button")




            _IEFormElementSetValue($emailform, $username1)
            _IEFormElementSetValue($usernameform, $password1)
            _IEAction($buttonweb, "click")

            Case $start
               _IENavigate($oIE, "http://addmefast.com/free_points/youtube_likes")
               sleep(2000)
               For $i = 1 To $repeat
                  Local $oInputs = _IETagNameGetCollection($oIE, "div")
                  For $oInput In $oInputs
                     If $oInput.classname == "btn3" Then _IEAction($oInput, "click")
                  Next

               Next

   EndSwitch
WEnd
EndFunc

It's at the end of the code, im trying to click on a button. The button does not have a name or id.

When you login to the site, click on youtube likes to the left. Now you see a button called like, how do I click that?

Local $oInputs = _IETagNameGetCollection($oIE, "div")
                  For $oInput In $oInputs
                     If $oInput.classname == "btn3" Then _IEAction($oInput, "click")
                  Next

This do not work because there is already another div (called Add site).

Thanks!

Replace your Loop with the click with:

           For $a In _IETagNameGetCollection($oIE, "a")
               If StringInStr(_IEPropertyGet($a, "innerText"), "Like") Then
                   For $i = 1 To $repeat
                        $a.fireEvent("onmousedown")
                        $a.fireEvent("onmouseup")
                        _IEAction($a, "click")
                        _IELoadWait($oIE)
                   Next
               EndIf
           Next

And it will click on something...
