Output Access Fields to Word Template (Office 2007)

I am trying to output some fields from a form to a word template (both are from Office 2007). The problem I am getting is that I click the button and Access freezes. It doesn't crash, but you can't do anything. I am using the code I got from the related question.

My version is posted below.

Private Sub btnCreateLetter_Click()
    Set strfrom = Me.OrderPickUp
    Set strto = Me.OrderDestination
    Set strdate = Me.OrderDate
    Set strtype = Me.WCCType
    Set strcosttpe = Me.WCCCostType
    Set strboxes = Me.WBox
    Set strcostboxes = Me.WCostBox
    Set strtotalex = Me.WTotalEx
    Set strtotalgst = Me.WTotalGST
    Set Strtotalincl = Me.WTotalInc
    Set wApp = CreateObject("Word.Application")
    Set wDoc = wApp.Documents.Add(Template:="C:\Users\Robert\Desktop\wcchup.dotx")
    For Each wSec In wDoc.Sections
   
           For Each wPara In wSec.Range.Paragraphs
            Select Case True                  
                Case InStr(1, wPara.Range.Text, "{from}") > 0
                    wPara.Range.Text = Replace(wPara.Range.Text, "{from}", strfrom)                    
                Case InStr(1, wPara.Range.Text, "{to}") > 0
                    wPara.Range.Text = Replace(wPara.Range.Text, "{to}", strto)                  
                Case InStr(1, wPara.Range.Text, "{date}") > 0
                    wPara.Range.Text = Replace(wPara.Range.Text, "{date}", strdate)                    
                Case InStr(1, wPara.Range.Text, "{time}") > 0
                    wPara.Range.Text = Replace(wPara.Range.Text, "{time}", strtime)                
                Case InStr(1, wPara.Range.Text, "{type}") > 0
                    wPara.Range.Text = Replace(wPara.Range.Text, "{tyoe}", strtype)                    
                Case InStr(1, wPara.Range.Text, "{costtype}") > 0
                    wPara.Range.Text = Replace(wPara.Range.Text, "{costtype}", strcosttype)                    
                Case InStr(1, wPara.Range.Text, "{boxes}") > 0
                    wPara.Range.Text = Replace(wPara.Range.Text, "{boxes}", strboxes)    
                Case InStr(1, wPara.Range.Text, "{costboxes}") > 0
                    wPara.Range.Text = Replace(wPara.Range.Text, "{costboxes}", strcostboxes)                  
                Case InStr(1, wPara.Range.Text, "{totalex}") > 0
                    wPara.Range.Text = Replace(wPara.Range.Text, "{totalex}", strtotalex)                    
                Case InStr(1, wPara.Range.Text, "{totalgst}") > 0
                    wPara.Range.Text = Replace(wPara.Range.Text, "{totalgst}", strtotalgst)                    
                Case InStr(1, wPara.Range.Text, "{totalincl}") > 0
                    wPara.Range.Text = Replace(wPara.Range.Text, "{totalincl}", Strtotalincl)

                End Select
   
        Next
    Next
 
    wApp.Visible = True
End Sub
