Using Excel VBA to select onchange value in javascript web

I am very new to VBA, I've been tried many times to use Excel VBA to select the value on a website, but it doesn't work. Below is the code I use. Actually I don't know how to get the elements since it has no "id" or "name" tag.

Sub GetFinanceData()

Dim URL As String

URL = "http://ift.tt/1Oo601c"

Set myIE = CreateObject("InternetExplorer.Application")

With myIE
.navigate URL
.Visible = True

Do While .Busy = True Or .readyState <> 4
Loop
DoEvents

.Document.parentWindow.execScript "selectData(zero);", "JavaScript"

End With

End Sub

Below is the HTML code, I want to change the option value to "zero" when open the website, can anybody help to check and advise what VBA code I can use to get the value "zero"? Thanks a lot in advance!

    <a name="a1" id="a1"></a>
        <div class="part02">
          <div class="sub01">
