I have Adobe Acrobat DC and am attempting to extract data from fillable pdf forms into an access database using Visual Basic for Appliactions and Java Script. My routines allow users to select a form to import and it loop through all fields and imports data into a table in db. This part works fine. The issue I am having is that sometimes the signatures show up as the first objects in the field colleciton as "Signature1", "Signature2", "Signature3", etc... These are always the first indexes in the collection instead of in the location they show up on the acutal form. Some forms when imported the signature fields actually have the actual field name such as "ApprovalSig" (for approvers) or "PointSig" for point of contact as identified on the form and in the proper order.
Code: This code was originally obtained from theDBGuy's PDF Form Fields Demo at accessmvp.com/thedbguy and modified for my purposes
On Error GoTo errHandler Dim appAcro As Object Dim docAcro As Object Dim docPD As Object Dim jso As Object Dim fd As Object Dim strFile As String Dim lngCounter As Long Dim fName As String Dim fValue As String Set fd = Application.FileDialog(3) 'filepicker 'select PDF file With fd .AllowMultiSelect = False .Filters.Clear .Filters.Add "PDF Files", "*.pdf" .Title = "Locate PDF file" If .Show Then strFile = .SelectedItems(1) Me.lblFilePath.Caption = strFile Set appAcro = CreateObject("Acroexch.AVDoc") If appAcro.Open(strFile, "") Then Set docPD = appAcro.getPDDoc() Set jso = docPD.getJSObject 'clear previous field list Me.txtFields = Null If jso.numFields > 0 Then For lngCounter = 0 To jso.numFields - 1 fName = jso.getNthFieldName(lngCounter) If jso.getfield(fName).Type = "signature" Then If jso.getfield(fName).SignatureInfo.Status <> 0 Then fValue = jso.getfield(fName).SignatureInfo.Name & " " & jso.getfield(fName).SignatureInfo.Date Else fValue = "Signature Missing" End If Else fValue = jso.getfield(fName).Value End If Me.txtFields = Me.txtFields & fName & "-" & fValue & vbCrLf 'Me.txtFields & jso.getNthFieldName(lngCounter) & "-" & jso.getfield(jso.getNthFieldName(lngCounter)).Value & vbCrLf Next MsgBox "Done!", vbInformation, "Demo" Else MsgBox "No form fields found!", vbInformation, "No Fields" End If 'Close the PDF; the True parameter prevents the Save As dialog from showing appAcro.Close True Else 'unexpected Acrobat error MsgBox "There was a problem reading the PDF file.", vbInformation, "Error" End If End If End With errExit: 'cleanup Set fd = Nothing Set jso = Nothing Set docPD = Nothing Set docAcro = Nothing Set appAcro = Nothing Exit Sub errHandler: MsgBox Err.Number & ": " & Err.Description Resume errExit
Why would the field indexes when looping through fields change, perhaps based on what app was used to complete the form?
Any help appreciated

The fields in a PDF are indexed according the order they appear in the document level field list, no physical location. They change when the form is edited in such a way as to change this field list. AFAIK: It doesn't have anything to do with the appliction that is calling the JS, the fields are always in the same order.
Why is the order a problem?

NVM. I figured it out. Users were drawing signatures instead of using the digital signature blocks provided.
