Excel 2010 Ribbon Calling Macros

Question

I have an Excel AddIn (.xlam file) and within it is a few macros and my attemt at a custom ribbon tab. The Macros work as expected but now I am trying to make a ribbon to call them to be more user friendly. I have the ribbon and a button which works, and a dropdown menu which I cannot figure out. I am unsure of what the Macro Parameters need to be. Below is what I have thus far.

The XML for the ribbon (Works!):

<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui">
  <ribbon>
    <tabs>
      <tab id="My_Tab" label="My Tab">
        <group id="NC_Material" label="Button1">
          <button id="Button1" label="1st button" size="large" onAction="Module1.Button1Click" imageMso="ResultsPaneStartFindAndReplace" />
          <dropDown id="DropDown" onAction="Module1.DropDownAction">
            <item id="ddmItem1" label="Item1" />
            <item id="ddmItem2" label="Item2" />
          </dropDown>
        </group >
      </tab>
    </tabs>
  </ribbon>
</customUI>

The VBA in Module1 of the .xlam files VBA Project:

'this one works
Public Sub Button1Click(ByVal control As IRibbonControl)
    call Button1Macro
End Sub

'this one does not work
Public Sub DropDownAction(ByVal control As IRibbonControl)
    call DropDownMacro
End Sub

I am getting errors when I change the value of the drop down menu in my ribbon. I do not know what parameters I need for the onAction macro of the drop down menu. I have been unable to find a good reference or example.

I am unable to do this using Visual Studio and cannot download any utilities or other programs.

Thanks in advance.

If you want to save your sanity, you can use Andy Pope's Ribbon Editor which will generate the callbacks automatically (at least the text for them). Then you just copy them into the VBA module. (I am not affiliated with that add-in, I just use it and recommend it highly)

Using that tool, I get the following for onAction within a Dropdown

Public Sub DropDownAction(control as IRibbonControl, id as String, index as Integer)
'
' Code for onAction callback. Ribbon control dropDown
'

End Sub

Working code is also shown in this answer which was near the top of my search.
