Form.Submit does not go through when using VBA

Question

I have a webpage that I am extracting data from. I can do everything fine with VBA apart from clicking on an image element which then submits a form and a popup with data is created.

One of the attributes in the image element is called "productguid" and has a string value =

"a12-545".

The HTML code of the form looks like this BEFORE I click on the image element with my mouse.

<form id="GetProductQuantitiesForAccessibleBranches" action="GetProductQuantitiesForAccessibleBranches" method="post">
  <input type="hidden" name="ProductGuid" value="">
</form>

This is the HTML code AFTER I manually click on it with the mouse:

<form id="GetProductQuantitiesForAccessibleBranches" action="GetProductQuantitiesForAccessibleBranches" method="post">
  <input type="hidden" name="ProductGuid" value="a12-545">
</form>

Based on this I assumed that the productguid value from the image element gets passed onto the form before it is submitted. Here is what my VBA code looks like this:

'Change the input element value
ie.Document.getElementById("GetProductQuantitiesForAccessibleBranches").all.item(0).value = "a12-545"

'Submit the form
ie.Document.getElementyId("GetProductQuantitiesForAccessibleBranches").Submit

According to the Locals window, all the Javascript events are Null. Both lines of code run without any errors but the webpage does not update. Am I missing something here?

I have also tried just clicking the image element with the .Click method, but that doesn't do anything either.

The webpage is password protected so I cannot post the URL publicly.

UPDATE:

Here is the HTML in the tag that normally is clicked manually which then submits the form. Perhaps there is something in here that I can use?

<img alt="View Quantities At Other Locations" src="/WebOrder/Images/CheckQtys.gif" 
title="View Quantities At Other Locations" class="popup" 
popupdirection="upperleft" popupwidth="380" 
popupcontent="#ProductQuantitiesForAccessibleBranches" 
onbeforepopupcreate="onBeforePopupCreate_GetProductQuantitiesForAccessibleBranches(this)" 
popupajaxformid="GetProductQuantitiesForAccessibleBranches" 
onbeforepopupajaxpost="onBeforePopupAjaxPost_GetProductQuantitiesForAccessibleBranches(this)" 
oncompletepopupajaxpost="onCompletePopupAjaxPost_GetProductQuantitiesForAccessibleBranches(this)" 
productguid="a12-545" 
displayitem="33902" 
brandguid="00000000-0000-0000-0000-000000000000" 
brandname="" brandsku="">

Give this a shot, I doubt this is going to be the 'perfect' answer without actually seeing the site. However, this should find the correct image tag, assuming you don't have any frames/iframes (please check there aren't any), and should click it.

Public Sub Click_IMG_Tag()
    Dim Elements As Object
    Dim Element  As Object

    'Get a pointer to IE etc first, I'm assuming this is already done

    Set Elements = IE.Document.getElementsByTagName("img")

    For Each Element In Elements
        On Error Resume Next ' used to bypass elements that don't have .Title property
                             ' later, you should error handle this exception
        If Element.Title = "View Quantities At Other Locations" Then
            Element.Focus
            Element.Click
            Element.FireEvent ("OnClick")
            IELoad IE
            Exit For
        End If
    Next

End Sub

Public Sub IELoad(Browser As Object)
    While Browser.busy Or Browser.Readystate <> 4
        Application.Wait (Now() + TimeValue("00:00:01"))
        DoEvents
    Wend
End Sub
