missing ; before statement

I've checked the other answers to similar questions - but so far no luck.

I have the following code:

$("#alphaindex").click(function(e) {      
                var item = $(this).attr("title");
                e.preventDefault(); 
                $.getJSON("getContacts.cfc?method=getContacts&returnformat=json",{"alpha":item}, function(res,code){
                    if(res.ROWCOUNT > 0){

                            s += "<h3 class='postTitle'>" + res.DATA.CONTACTFIRSTNAME[i] res.DATA.CONTACTLASTNAME[i] + "</h3>"
                            + "<p class='postDesc'>" + res.DATA.CONTACTEMAIL[i] + "</p>"
                            + "<p class='postDesc'>" + res.DATA.CONTACTMOBILE[i] + "</p> <br class='clr' />"
                            };
                        s += "";
                        } 
                    else {
                        var s = "Sorry, nothing matched your search.";
                    }
                    $("#results").html(s);

                    },"json");
                })
            });

and I'm getting the ; missing before statement message in relation to the line:

s += "<h3 class='postTitle'>...res.DATA.CONTACTLASTNAME[i] + "</h3>" 

according to firebug.

I'm sure it's something obvious - hopefully your eyes will spot it where mine have failed!

Aren't you missing a + sign between these two in that line?

res.DATA.CONTACTFIRSTNAME[i] res.DATA.CONTACTLASTNAME[i]
