Are these comoboxes from the control toolbox toolbar or from the forms toolbar?
for control toolbox:
Dim sh as Worksheet, obj as OleObject
Dim msg as Variant
for sh in thisworkbook.worksheets
for each obj in sh.OleObjects
if typeof obj.Object is MSForms.Combobox then
if obj.Object.Value = "" then
Msg = MsgBox("All questions have not been completed. " & _
" Please double-check the drop down boxes to ensure no " & _
"questions were left unanswered.", vbOKOnly, "Missing Answers")
exit sub
end if
end if
Next
Next
for forms toolbar:
Dim sh as Worksheet, cbox as DropDown
for each sh in ThisWorkbook.Worksheets
for each cbox in sh.Dropdowns
if cbox.Value = "" then
Msg = MsgBox("All questions have not been completed. " & _
" Please double-check the drop down boxes to ensure no " & _
"questions were left unanswered.", vbOKOnly, "Missing Answers")
exit sub
End if
Next
Next

Thank you, Tom. The combo-boxes are controls, not forms. Your code
worked very well, with the exception of one minor detail. The code
checks all sheets in the workbook, what if I needed it to only
reference one sheet? Is there a way to specify the worksheet? I will
try to solve this, but if you have the answer, I would greatly
appreciate it.
Thanks again for your help!

I checked all sheets because the sample code you posted appeared to be doing
that. Certainly you can just set the variable Sh to refer to a single sheet
and remove that outer loop.
Dim sh as Worksheet, obj as OleObject
Dim msg as Variant
set sh = worksheets("Sheet1")
for each obj in sh.OleObjects
if typeof obj.Object is MSForms.Combobox then
if obj.Object.Value = "" then
Msg = MsgBox("All questions have not been completed. " & _
" Please double-check the drop down boxes to ensure no " & _
"questions were left unanswered.", vbOKOnly, "Missing Answers")
exit sub
end if
end if
Next
