RUN TIME ERROR 462 - GRAHAMSCAN HELP?

I have a math test all set up and is attached as a WORD document.  It has 15 questions, each followed by an empty area where students can input work.  After the work area is 4 multiple choice checkboxes where the students can pick the answer that matches their work.  Right now the correct answers are selected, but you can change the selections to test the macro below.  The test has to be located in the C:\ directory for the macro below to find it.

I have an excel file attached which has a macro that goes out and reads the checkboxes and compares them to a table in the Excel file with the correct answers.  The maco fills in a SCORES column for each of 15 questions.  If the student inputs the correct answers the score is 1, if not the score is 0, a SUM function calculates a grade.  If the student inputs more than one checkbox answer, that question is scored as a 0.

The problem is weird.  If I run the macro once, it works.  If I run it again I get an error 462 "The remote server machine does not exist or is unavailable".  Every odd time I run it, it runs.  Every even time I run it it fails.  If I run the macro, hit the reset in the RUN menu, and run it, it runs every time.

What is going on?

On your macro, change ActiveDocument to appWord

It couldn't find what the "ActiveDocument" was.

See attached code
Sub readtest()
   Dim TestPath As String
   Dim appWord As Word.Application, docWord As Word.Document
   Dim ffcb As FormField 'formfield checkbox
   Dim bValue As Boolean
   Dim ffdd As FormField 'formfield dropdown
   Dim strValue As String
   Dim iListIndex As Integer
   Dim CheckboxName As String
   Dim TestProblem As Integer
   Dim BoxNumber As Integer
   Dim cbCounter As Integer
   Dim cbCounterStr As String
   Dim Msg As String
   Dim Score As Integer
   Dim CellRow As Integer
   Dim CellCol As Integer
   Dim CheckboxSum As Integer
   Dim StudentBox As Integer
   Dim CorrectAns As Integer
   Dim doc As Word.Document
   

   Set appWord = New Word.Application
   appWord.Visible = True
   TestPath = "C:\"
   Set docWord = appWord.Documents.Open(TestPath & "student-ct1.doc")
   Application.EnableEvents = False
   'MsgBox "doc opened"
   
   'now read the pull downs and checkboxes
   Set ffdd = docWord.FormFields("Dropdown1")
   iListIndex = ffdd.DropDown.Value
   strValue = ffdd.DropDown.ListEntries(iListIndex).Name
   'MsgBox strValue
   
   For TestProblem = 1 To 15
     CellRow = TestProblem + 4
     For BoxNumber = 1 To 4
       'Read the problem's checkboxes
         cbCounter = ((TestProblem - 1)) * 4 + BoxNumber
         cbCounterStr = cbCounter
         CheckboxName = "Check" & cbCounterStr
         Set ffcb = ActiveDocument.FormFields(CheckboxName)
         bValue = ffcb.CheckBox.Value
         If bValue = False Then StudentBox = 0
         If bValue = True Then StudentBox = 1
       'Read the corresponding correct answer
         CellCol = BoxNumber + 2
         CorrectAns = Cells(CellRow, CellCol).Value
       'If one of more boxes disagree the score is 0 for this problem
         'Msg = "Problem " & TestProblem & "Box " & BoxNumber & " Student Ans " & StudentBox & "Correct Ans " & CorrectAns
         'MsgBox Msg
         If StudentBox <> CorrectAns Then
           Cells(CellRow, 8) = 0
           BoxNumber = 4
         Else
           Cells(CellRow, 8) = 1
         End If
     Next
   Next
     
   docWord.Close
   appWord.Quit
   Application.EnableEvents = True
   Set docWord = Nothing
   Set appWord = Nothing
End Sub

Open in new window

I did not get it to work changing activedocument to appWord, but did if I changed it to docWord.
Going to test it some more, may have another question....

A little confused about why the DIM statements set variables to FORMFIELD but in the text they are used as FORMFIELDS.  The macro does not work if they are used as FORMFIELD in the body; errors.

Seems like a slight mod to the suggested solution works.
