Clicking Select All in this HTML window - html

Question

Help Everyone,
I have VBA code to open up the report picture as shown below, it will select ERX IE WORKFUSION HOA from the first drop-down list, click View Report (as that is the only way to show the options in the User drop-down box), and then I want it to select "Select All" from the User list. Unfortunately, the User list is not created the same way in HTML as the User Group one, so I cannot mimic what I've done there.
I am getting a Run-time error 91: Object variable or With block variable not set error on the following line near the bottom .document.getelementbyId("ct132_ct104_ct107_divDropDown_ct100").Click
Sub Import_DCTR_Bot_Prod()
'Set Variables
Dim IE As InternetExplorerMedium
Dim targetURL As String
Dim webcontent As String
Dim sh
Dim eachIE
targetURL = "http://lousrswpl10:8081/Reports/Pages/Report.aspx?ItemPath=%2f12717%2fReports%2fWorkflow%2fePostRx+Detailed+Audit+Report&ViewMode=Detail"
Set IE = New InternetExplorerMedium
IE.Visible = True
IE.navigate targetURL
'Navigate to ePostRx Detailed Audit Report
While IE.Busy
DoEvents
Wend
Do
Set sh = New Shell32.Shell
For Each eachIE In sh.Windows
If InStr(1, eachIE.LocationURL, targetURL) Then
Set IE = eachIE
Exit Do
End If
Next eachIE
Loop
Set eachIE = Nothing
Set sh = Nothing
While IE.Busy
DoEvents
Wend
'Select ERX IE WORKFUSION HOA from User Group
With IE
.Document.getElementById("ctl32_ctl04_ctl05_ddValue").Value = "42"
.Document.Forms(0).submit
End With
With IE
.Document.getElementById("ct132_ct104_ct107_divDropDown_ct100").Click
End With
End Sub
Here's what the HTML says on the actual Select All checkbox:
<INPUT onclick="$get('ctl32_ctl04_ctl07').control.OnSelectAllClick(this);" id=ctl32_ctl04_ctl07_divDropDown_ctl00 type=checkbox value="" name=ctl32$ctl04$ctl07$divDropDown$ctl00>
