VBA Type missmatch - vba

Question

I have wrote some VBA code which I was fairly happy with. It went through a list on a worksheet, switched to another and set a variable (and thus changed some graphs) and then opened word, copied in the graphs to various bookmarks and saved the document as the variable name.
It worked like a charm and I was a happy boy (saved a good week and a bit of work for someone). I have not touched it since - or the worksheets for that matter - opened it today and it is giving me a type missmatch on the first lot. I would really love some advice as it has left me scratching my head.
Public X As Integer
Public Y As String
Sub Macro2()
'Set up variables that are required
Y = ""
LoopCounter = 2
Do Until Y = "STOP"
'Grab the value from a list
Sheets("CPD data 13-14").Select
Range("A" & LoopCounter).Select
Y = Range("A" & LoopCounter).Value
'Change the chart values
Sheets("Pretty Display (2)").Select
Range("A1").Value = Y
'Open word template
Set wordapp = CreateObject("word.Application")
wordapp.documents.Open "LOCATION"
wordapp.Visible = True
wordapp.Activate
wordapp.ActiveDocument.Bookmarks("InstitutionName").Range = Y
wordapp.ActiveDocument.Bookmarks("Graph1").Range = ActiveSheet.ChartObjects("Chart 3")
'Close document
Mystring = Replace(Y, " ", "")
wordapp.ActiveDocument.SaveAs Filename:="LOCATION" & Mystring & ".docx"
wordapp.Quit
Set wordapp = Nothing
'Increase count and loop
LoopCounter = LoopCounter + 1
Loop
The error hits on the following line:
wordapp.ActiveDocument.Bookmarks("Graph1").Range = ActiveSheet.ChartObjects("Chart 3")
EDIT
As suggested I have updated my code not to use select so it now reads:
Set ws = Sheets("CPD data 13-14")
Set pd = Sheets("Pretty Display (2)")
'Set up variables that are required
Y = ""
LoopCounter = 2
Do Until Y = "STOP"
'Grab the value from a list
Y = ws.Range("A" & LoopCounter).Value
'Change the chart values
pd.Range("A1").Value = Y
'Open word template
Set wordapp = CreateObject("word.Application")
wordapp.documents.Open "LOCATION"
wordapp.Visible = True
wordapp.Activate
wordapp.ActiveDocument.Bookmarks("InstitutionName").Range = Y
wordapp.ActiveDocument.Bookmarks("Graph1").Range = pd.ChartObjects("Chart 3")
'Close document
Mystring = Replace(Y, " ", "")
wordapp.ActiveDocument.SaveAs Filename:="LOCATION" & Mystring & ".docx"
wordapp.Quit
Set wordapp = Nothing
'Increase count and loop
LoopCounter = LoopCounter + 1
Loop
I still get the same runtime error at the same point.

Answer 1

try this
Option Explicit
Public X As Integer
Public Y As String
Sub Macro2()
Dim wordApp As Object
Dim LoopCounter As Integer
Dim Mystring As String
Dim ws As Worksheet, pd As Worksheet
Set ws = Sheets("CPD data 13-14")
Set pd = Sheets("Pretty Display (2)")
'Set up variables that are required
Y = ""
LoopCounter = 2
' open one Word session for all the documents to be processed
Set wordApp = CreateObject("word.Application")
Do Until Y = "STOP"
'Grab the value from a list
Y = ws.Range("A" & LoopCounter).Value
With pd
.Range("A1").Value = Y 'Change the chart values
.ChartObjects("Chart 3").Copy ' Copy the chart
End With
'act on Word application
With wordApp
'open word template
.documents.Open "LOCATION"
.Visible = True
' paste into bookmarks, "save as" document and close it
With .ActiveDocument
.Bookmarks("InstitutionName").Range = Y
.Bookmarks("Graph1").Range.PasteSpecial
Mystring = Replace(Y, " ", "")
.SaveAs Filename:="LOCATION" & Mystring & ".docx"
.Close
End With
End With
'Increase count and loop
LoopCounter = LoopCounter + 1
Loop
'Close Word
wordApp.Quit
Set wordApp = Nothing
End Sub
I couldn't have a word "Range" object directly set to an Excel "Chart" object
So I had to copy the chart and use "PasteSpecial" method of the Word "Range" object
Furthemore I worked with one Word session only, which'd result in a faster job
Finally I also made some "comsetics" to make the code more readable/maintanable
just as a suggestion: I'd always use "Option Explicit" statement. that'll force you some extra work to explicitly declare each and every variable you use, but that will also give much more control over your work and result in less debbugging issues, thus saving time at the end

Answer 2

My advice is to set the Explicit flag and try to decompile the code. Any variables that you didn't dimension will throw an error. This is a good time to dimension the variable and type the data appropriately.
If that doens't throw an error, which it should since you have at least one variable LoopCounter that isn't dimensioned and could therefore cause data type errors then try changing Public X As Integer to Public X As Long so as to avoid values beyond the limit of the Integer data type.
.Activate is sometimes necessary even when using .Select from my experience. Selecting a worksheet should make it the active worksheet, but that's not always the case.
