In order to Automate with Word, there are a couple of things we need to take care of.
References
When manipulating Word from Access, we will need to have access to a library of objects and methods associated with Word. These will need to be referenced in VBA and here is how you do it:
Open up the database.
Press ALT+F11 to open up the VBA editor.
Click on the tools drop down menu and choose References.
Scroll down and find Microsoft Office 15.0 Library (12.0 for 2007, 14.0 for 2010). This library is a generic library that will enable you to use objects such as recordsets. Check the box.
Scroll down and select Microsoft Word 15.0 Object Library (12.0 for 2007, 14.0 for 2010). This library will enable you to interact with Word objects and methods. Check the box.
Click OK and the dialog form will close.
Reopen the dialog form and you should see that the Word and Office libraries are checked.
You now have the requisite libraries to enable you to automate Word!
