Ah, as so often happens the multi-select-listbox bytes again... punny
As seen here:
http://bytes.com/topic/access/answer...select-listbox (don't bother to follow the links in this thread, they are all long dead; thus, the code they reference is no longer available) you basically need to pass a record set to the word document and that's not what is happening with your document. The control isn't part of any recordset... nor to the best of my knowledge can it be used that way directly.
So in order to do anything with the control, you'll need to understand how a multiselect works and the common methods of retrieving the information out of the control:
ListBox.MultiSelect Property (Access)
Office 2010 One Method to get the selected information Use a multi-select list box to filter a report - Allen Browne
Mr. Browne most likely has the easiest to follow methods... but I'm a little bias here given the amount of help his site has given me over the years.
From here, we're going to need to either store the query that you will create using the control's values- and then you can open the word document by hand (IMHO the easiest for newer VBA programmers or for those just occational type merges), store the query and then call word to open with the mail merge document that has already been linked to a query with that name, or pass the query via application automation. However, it really depends on your skill set as to the best method to use to get your information out to word.
To give you an example of application automation read thru the following insight article:
Application Automation now this does deal with Outlook and Excel; however, word is essentially the same basic principles

Please attempt one method or the other.
