setting up reduce function... error on import

[Chris Johnson]

I am new to couch and trying to get my arms around the map/reduce 
function. I am using exmaples from the web as well as the tutorials in 
the O'Reilly book as a guide. I have an understanding of the map 
function, but when I try to introduce the reduce function to my file I 
get a bad request error when I try to import it.

{"error":"bad_request","reason":"invalid UTF-8 JSON"}
Basically what I am doing is importing a session table from a firewall 
into couch and then using a reduce function to count the number of 
sessions for a given host. What I have is

{
    "_id" : "_design/example",
    "_rev" : "8-849766ce1eb8eedaa2353a408a3aaaf2",
    "views" : {
        "foo" : {
            "map" : "function(doc){
                if(doc.in_dstPort == '443') emit(doc.in_dstIP, 1);
            }"

            "reduce" : "function(key, values, rereduce){
                return sum(values);
            }"

        }
    }
}

I have narrowed it down the to the reduce function but just cant seem to 
isolate the issue. I know it is something minor that I am missing.

Thanks in advance for your help
