Translating file associations in VBA - vba

Question

All right, this is my second attempt at a code, and the second VBA macro project I've been assigned to work on. I've been working to learn VBA as my first coding language for the last week and a half, so I apologize for silly mistakes. That said, straight to business. Here's what I put together for a word document macro:
Sub MacroToUpdateWordDocs()
'the following code gets and sets a open file command bar for word documents
Dim Filter, Caption, SelectedFile As String
Dim Finalrow As String
Dim FinalrowName As String
Filter = "xlsx Files (*.xlsx),*.xlsx"
Caption = "Please Select A .xlsx File, " & TheUser
SelectedFile = Application.GetOpenFilename(Filter, , Caption)
'check if value is blank if it is exit
Finalrow = Cells(Rows.Count, 1).End(xlUp).Row
FinalrowName = Finalrow + 1
If (Trim(SelectedFile) = "") Then
Exit Sub
Else
'setting up the inital word application object
Set auditmaster = CreateObject("excel.sheet")
'opening the document that is defined in the open file dialog
auditmaster.Application.Workbooks.Open (SelectedFile)
'ability to change wether it needs to burn cycles updating the UI
auditmaster.Visible = False
'declare excel sheet
Dim wdoc As Document
'set active sheet
Set wdoc = Application.ActiveDocument
Dim i As Integer
Dim u As Integer
Dim ColumnAOldAddy As String
Dim ColumnCNewAddy As String
u = 1
i = 1
'MsgBox (wordapp.ActiveDocument.Hyperlinks.Count)
'Sets up a loop to go through the Excel Audit file rows.
For i = 1 To auditmaster.ActiveSheet.Rows.Count
'Identifies ColumnAOldAddy and ColumnCNewAddy as columns A and C for each row i. Column A is the current hyperlink.address, C is the updated one.
ColumnAOldAddy = auditmaster.Cells(i, 1)
ColumnCNewAddy = auditmaster.Cells(i, 3)
'If C has a new hyperlink in it, then scan the hyperlinks in wdoc for a match to A, and replace it with C
If ColumnCNewAddy = Not Nothing Then
For u = 1 To doc.Hyperlinks.Count
'If the hyperlink matches.
If doc.Hyperlinks(u).Address = ColumnAOldAddy Then
'Change the links address.
doc.Hyperlinks(u).Address = ColumnCNewAddy
End If
'check the next hyperlink in wdoc
Next
End If
'makes sure the macro doesn't run on into infinity.
If i = Finalrow + 1 Then GoTo Donenow
'Cycles to the next row in the auditmaster workbook.
Next
Donenow:
'Now that we've gone through the auditmaster file, we close it.
auditmaster.ActiveSheet.Close SaveChanges:=wdDoNotSaveChanges
auditmaster.Quit SaveChanges:=wdDoNotSaveChanges
Set auditmaster = Nothing
End If
End Sub
So, this code is suppose to take a hyperlink audit file created by my first macro (The last bugs fixed and functioning wonderfully thanks to the Stack Overflow community!). The audit file has 3 columns and a row for each hyperlink it found in the target .docx: A = hyperlink address, B = Hyperlink displaytext, and C = the new Hyperlink address
When the code runs from the .docx file to be updated, it allows the user to choose the audit file. From there, it goes row by row to check if an updated hyperlink address has been written into the C column by the older audited address/display name, then searches the .docx file for the old hyperlink address and replaces it with the new hyperlink address. At that point, it finishes searching the document then moves on to the next row in the audit excel file.
My problem is that much of this code is copy/pasted out of code from an excel macro. I have been having a hell of a time figuring out how translate that code into something that identifies/references the word/excel documents appropriately. I'm hoping someone with more experience can take a peek at this macro and let me know where I've completely buggered up. It keeps giving me "Method or data member not found" errors all over the place currently, primarily concerning where I attempt to reference the audit excel file. I'm pretty sure that this is a relatively easy fix, but I don't have the vocabulary to figure out how to Google the answer!

Compiled OK, but not tested:
Sub MacroToUpdateWordDocs()
Dim Filter, Caption, SelectedFile As String
Dim Finalrow As String
Dim appXL As Object
Dim oWB As Object
Dim oSht As Object
Dim wdoc As Document
Dim ColumnAOldAddy As String
Dim ColumnCNewAddy As String
Dim i As Long
Dim h As Word.Hyperlink
Dim TheUser As String
Filter = "xlsx Files (*.xlsx),*.xlsx"
Caption = "Please Select A .xlsx File, " & TheUser
Set appXL = CreateObject("excel.application")
appXL.Visible = True
SelectedFile = appXL.GetOpenFilename(Filter, , Caption)
appXL.Visible = False
If Trim(SelectedFile) = "" Then
appXL.Quit
Exit Sub
Else
Set oWB = appXL.Workbooks.Open(SelectedFile)
Set oSht = oWB.worksheets(1)
Finalrow = oSht.Cells(oSht.Rows.Count, 1).End(-4162).Row '-4162=xlUp
End If
Set wdoc = Application.ActiveDocument
For i = 1 To Finalrow
ColumnAOldAddy = oSht.Cells(i, 1).Value
ColumnCNewAddy = oSht.Cells(i, 3).Value
If ColumnCNewAddy <> ColumnAOldAddy Then
For Each h In wdoc.Hyperlinks
If h.Address = ColumnAOldAddy Then
h.Address = ColumnCNewAddy
End If
Next h
End If
Next i
oWB.Close False
appXL.Quit
End Sub
