Browse for file in form

[Jason V]

I want the user to be able to browse for a file and when chosen, the file
name and path are inserted in the unbound Text box that started the event. I
have found much reference to the below code but I don't know how to make it
work in my database.

API: Call the standard Windows File Open/Save dialog box

Do I just copy and paste the code into my VBA window? When I do I get an
error, "Only comments may appear after End Sub, End Function, or End
Property".

Thanks
