Stupid question: give user pop-up box to open or save file

I have a very simple page that shows a list of names and links to
a .pdf file associated to each name.  The code is below.  When a user
clicks on the "Save" button, I would like them to get the popup box
that asks if they want to save or open the do***ent; however, I can't
get that to work - it just opens the .pdf.

It has to be something really easy...can someone help?  I've been
having one of those days...I should probably just go home.

thanks!

			<!--- get list of PDFs --->
			<cfoutput query="candidateFiles">
				<!--- split the file names into usable output --->
				<cfset LastName = #GetToken(name, 1, "_")#>
				<cfset FirstName = #GetToken(name, 2, "_")#>
				<cfset FirstName = #GetToken(FirstName, 1, ".")#>
				<tr>
					<td id="listData">
