javascript ate my cereal!

I'm trying to code a simple countdown timer for a friend, but the code as it is now will run once, then return NaNs for the numbers. Eventually it will start working under safari, but not under IE or Mozilla. Any suggestions?

Code:

<FORM name=count>

        <INPUT size=73 name=count2>

</FORM>



<SCRIPT>



//Count down until any date and time





var until='Party'

var current='A Title of some sort to display when time is up'

var montharray=new Array('Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec')



function countdown(yr,mth,day,hour,min,sec)

{

        theyear=yr;themonth=mth;theday=day;thehr=hour;themin=min;thesec=sec

        var today=new Date()

        var todayy=today.getYear()

        if (todayy < 1000)

                todayy+=1900

        var todaym=today.getMonth()

        var todayd=today.getDate()

        var todayh=today.getHours()

        var todaymin=today.getMinutes()

        var todaysec=today.getSeconds()



        var todaystring=montharray[todaym]+' '+todayd+', '+todayy+' '+todayh+':'+todaymin+':'+todaysec

        

        futurestring=montharray[mth-1]+' '+theday+', '+theyear+' '+thehr+':'+themin+':'+thesec

        



        dd=Date.parse(futurestring)-Date.parse(todaystring)

        dday=Math.floor(dd/(60*60*1000*24)*1)

        dhour=Math.floor((dd%(60*60*1000*24))/(60*60*1000)*1)

        dmin=Math.floor(((dd%(60*60*1000*24))%(60*60*1000))/(60*1000)*1)

        dsec=Math.floor((((dd%(60*60*1000*24))%(60*60*1000))%(60*1000))/1000*1)



        if(dday==0&&dhour==0&&dmin==0&&dsec==0)

        {

                document.forms.count.count2.value=current

                return

        }

        else

                document.forms.count.count2.value='Only '+dday+ ' days, '+dhour+' hours, '+dmin+' minutes, and '+dsec+' seconds left until '+until



        setTimeout('countdown(theyear,themonth,theday,themin,thesec)',1000)

}

//enter the count down date using the format year/month/day/hour/minute/seconds



countdown(2004,4,15,0,0,0)

Awsome, thank you!

Though I don't know why it didn't work the way it was before.
