Drop Down List Box from an Array?

Question

I have an array - a lovely little 1-dimensional array of customer last names - that I want to display in a drop down list box so my user can begin to type a value in that list box and CF will bring up the matching entry.
I have tried cfloop and cfselect, but haven't had any success. Once the user clicks on a name, I want to be able to take that value and do some other processing.
  Any suggestions?

No Ajax - CF is a ***** enough as it is.
OK - I see where you started to go with your link, but lost you somewhere in Step 2.
I like the idea of a master query with sub queries off of it (Queries of Queries).  Here's what I got so far:
<cfquery 
name = "MasterMemberQuery" datasource = "cfissues">
        SELECT *  FROM Members  
        ORDER BY LastName</cfquery>
  <cfquery  name = "LastNameQry" dbtype = "query">
     SELECT MemberID, LastName  
     FROM MasterMemberQuery  
    ORDER BY LastName</cfquery>
This worked perfectly - nice cfselect to display the last names - just like before.  However, I still cannot capture the user's choice from the cfselect statement:
<cfform> 
      <cfselect name = "ChosenLastName"  
                    query = "LastNameQry"  
                    value = "MemberID"  
                    display = "LastName"  
                    size = "1">  
     </cfselect>
     <cfoutput>
               The chosen MemberID = '#LastNameQry.MemberID#'
     </cfoutput>
</cfform>
The name "ChosenLastName" is always labelled as invalid, and the cfoutput always gives the MemberID of the first entry in the LastNameQry, never the user's choice. 
I need to take the user's choice of last name, capturing the MemberID (the value attribue of the cfselect) and read the MasterMemberQuery to get just the single member's data.
And is it me or does this forum's site run at about 300 baud?????
