Open Word mail merge file from excel button

I need a code that will open my mail merge document from excel. I want to be able to click the button and have word automatically open to my mail merge document. My Word document already has the merge fields and labels updated. I just need to open word to make it as user friendly as I can for others who are not as familiar with excel and word. I am very new to VBA; however I can get my Word document to open but it doesn't allow me to use the mail merge features. These features are greyed out and I can't even select the "Finish Merge" tab, nor does the SQL question appear asking that is already linked to my excel sheet. Here is all I got so far:

Sub Print_Tags()
Set wordApp = CreateObject("word.Application")

wordApp.documents.Open "C:\Users\J.Templet\Desktop\LOTO Print Tags\PRINTING TAGS1.docx"

wordApp.Visible = True

End Sub

Please help!!

So I have tried numerous things but I keep getting the same debug issue "Run time Error 424, object needed" I would really appreciate any help with this. Here is the latest on what I have.

Sub Print_Tags()

Set wordapp = CreateObject("word.Application")

wordapp.documents.Open "C:\Users\J.Templet\Desktop\LOTO Print Tags\PRINTING TAGS.dotx"

wordapp.Visible = True

WordBasic.MailMergePropagateLabel
With docwd.MailMerge
.Destination = wdSendToNewDocument
.SuppressBlankLines = True
With .DataSource
.FirstRecord = wdDefaultFirstRecord
.LastRecord = wdDefaultLastRecord
End With
.Execute Pause:=False
End With
End Sub


This is the part that is highlighted yellow when I open the debug VBA:

docwd.MailMerge.OpenDataSource Name:= _
"C:\Users\J.Templet\Desktop\LOTO Print Tags\Isolation LOTO Template.xlsx" _
, ConfirmConversions:=False, ReadOnly:=False, LinkToSource:=True, _

Did you get an answer to your question? When in Word did you associate the Excel spreadsheet with the Merge Document?
