Setting Document Measurement Units

Thanks, I changed the syntax but it still doesn't seem to work.

I see an error 424 in the log now. VB error descriptor says 'Object Required.' What am I missing here?

          Set myDocument = myInDesign.Documents.Add
          Set oArgs = WScript.Arguments.Unnamed
          objTextFile.WriteLine("InDesign after Add Docs")
     If Err.Number <> 0 then
       objTextFile.WriteLine("After Obj  Error = " & Err.Number)
     End If
     Err.Clear     
          myDocument.marginPreferences.left = 0
          myDocument.marginPreferences.right = 0
          myDocument.marginPreferences.top = 0
          myDocument.marginPreferences.bottom = 0
     If Err.Number <> 0 then
       objTextFile.WriteLine("Set Margins: Error = " & Err.Number)
     End If
     Err.Clear
          myDocument.ViewPreferences.HorizontalMeasurementUnits = idMeasurementUnits.idInches
          myDocument.ViewPreferences.VerticalMeasurementUnits = idMeasurementUnits.idInches
     If Err.Number <> 0 then
       objTextFile.WriteLine("Set Measurement Units: Error = " & Err.Number)
     End If
     Err.Clear
          Set myPage = myDocument.pages(1)
          myPage.marginPreferences.left = 0
          myPage.marginPreferences.right = 0
          myPage.marginPreferences.top = 0
          myPage.marginPreferences.bottom = 0

          With myDocument.DocumentPreferences
          .PageHeight = oArgs.Item(1)
          .PageWidth =  oArgs.Item(2)
          .PagesPerDocument = 1
          End With

I think I had a similar problem before where the id___.id___ values were not working. To set UserInteractionLevel, I had to find the numeric value of idNeverInteract. Do you know why this is happening? Is there somewhere I can find a conversion for the id's?

Is this you?! If so, you are a prince among men. Thank you.

Yes, we usually write JS, but in this case I was augmenting an existing resource.

Thanks again.
