Wrongly Entered Readers Field in Lotus Notes Document

Mistakenly while updating the document through LotusScript I have appended some value in and item which was basically a notes reader field on the form. Now the problem is that this document has not been accessed by anyone not even the one who created it. What can I do?? Can I retrieve the document and update the reader field?? Is there any method ?? The code for updating the reader field notesitem is attached for reference.
I don't know what went wrong because same code is running perfectly fine in an other database.

Dim s As New NotesSession
	Dim db As NotesDatabase
	Dim docs As NotesDocumentCollection
	Dim n As NotesName
	Dim ws As New NotesUIWorkspace
	Dim nameVar As Variant
	Dim doc As NotesDocument
	Dim item As NotesItem
	
	Set db = s.Currentdatabase
	Set docs = db.Unprocesseddocuments
	nameVar = ws.Pickliststrings(PICKLIST_NAMES)
	If nameVar(0) = "" Then
		Msgbox "Please select any name to continue",64,db.title
		Exit Sub
	Else
		Set n = New NotesName(nameVar(0))		
	End If
	
	Set doc = docs.Getfirstdocument()
	If doc Is Nothing Then
		Msgbox "No document is selected, Can't proceed",64,db.Title
		Exit Sub
	End If
	If ws.prompt(PROMPT_YESNO,db.Title,"This will change current desk to the selected user in selected document, Do you wish to continue?")Then
		While Not doc Is Nothing			
			doc.CurrentApprover = n.Abbreviated			
			Set item = doc.Getfirstitem("WorkflowReaders")
			If Not item Is Nothing Then
				Call item.Appendtotextlist(n.abbreviated)
			End If
			Set item = doc.Getfirstitem("fl_Readers")
			If Not item Is Nothing Then
				Call item.Appendtotextlist(n.abbreviated)
			End If
			
			Call doc.Save(True,False)		
			Set doc = docs.Getnextdocument(doc)
		Wend
	End If
