Hi all,

I'm using a small javascript which counts the time since a particular datetime value. I can use the script once on the page, but if i try and access it a second time it doesn't work. What i mean is:

The script in <body> is:

Code:
<script language="JavaScript">
 TargetDate = "06/20/2013 00:00:01";
 FinishMessage = "done"
 BackColor = "white";
 ForeColor = "black";
 CountActive = true;
 LeadingZero = true;
 DisplayFormat = "%%D%% Days %%H%%:%%M%%:%%S%% ";
 </script>
<script type="text/javascript"  language="JavaScript" src="time.js"></script>
time.js is

Code:
<script>function calcage(secs, num1, num2) {
  s = ((Math.floor(secs/num1))%num2).toString();
  if (LeadingZero && s.length < 2)
    s = "0" + s;
  return  s;
}

function CountBack(secs) {
  if (secs < 0) {
    document.getElementById("cntdwn").innerHTML = FinishMessage;
    return;
  }
  DisplayStr = DisplayFormat.replace(/%%D%%/g, calcage(secs,86400,100000));
  DisplayStr = DisplayStr.replace(/%%H%%/g, calcage(secs,3600,24));
  DisplayStr = DisplayStr.replace(/%%M%%/g, calcage(secs,60,60));
  DisplayStr = DisplayStr.replace(/%%S%%/g, calcage(secs,1,60));

  document.getElementById("cntdwn").innerHTML = DisplayStr;
  if (CountActive)
    setTimeout("CountBack(" + (secs+CountStepper) + ")", SetTimeOutPeriod);
}

function putspan(backcolor, forecolor) {
 document.write("<span id='cntdwn'></span>");
}

if (typeof(BackColor)=="undefined")
  BackColor = "white";
if (typeof(ForeColor)=="undefined")
  ForeColor= "#2A8827";
if (typeof(TargetDate)=="undefined")
  TargetDate = "12/31/2020 05:00:00";
if (typeof(DisplayFormat)=="undefined")
  DisplayFormat = "%%D%% days, %%H%% hours, %%M%% minutes, %%S%% seconds.";
if (typeof(CountActive)=="undefined")
  CountActive = true;
if (typeof(FinishMessage)=="undefined")
  FinishMessage = "no data";
if (typeof(CountStepper)!="number")
  CountStepper = +1;
if (typeof(LeadingZero)=="undefined")
  LeadingZero = true;


CountStepper = Math.ceil(CountStepper);
if (CountStepper == 0)
  CountActive = false;
var SetTimeOutPeriod = (Math.abs(CountStepper)-1)*1000 + 1000;
putspan(BackColor, ForeColor);
var dthen = new Date(TargetDate);
var dnow = new Date();
if(CountStepper>0)
  ddiff = new Date(dnow-dthen);
else
  ddiff = new Date(dthen-dnow);
gsecs = Math.floor(ddiff.valueOf()/1000);
CountBack(gsecs);</script>
However, if i want to use the script twice, to display the amount of time since another datetime value, inly the first is displayed. This is what i have tried but no joy.

Code:
<script language="JavaScript">
 TargetDate = "06/20/2013 00:00:01";
 FinishMessage = "done"
 BackColor = "white";
 ForeColor = "black";
 CountActive = true;
 LeadingZero = true;
 DisplayFormat = "%%D%% Days %%H%%:%%M%%:%%S%% ";
 </script>

<script language="JavaScript">
 TargetDate = "06/19/2013 00:00:01";
 FinishMessage = "done"
 BackColor = "white";
 ForeColor = "black";
 CountActive = true;
 LeadingZero = true;
 DisplayFormat = "%%D%% Days %%H%%:%%M%%:%%S%% ";
 </script>

<script type="text/javascript"  language="JavaScript" src="time.js"></script>
I guess the reason it doesn't work is because there are two values for TargetDate and the script just uses the first one? Is there a way of getting it to work so that i can use this multiple times on the page?

Any help would be greatly appreciated,

many thanks.
