Button inactive after 60secs

[jmcg]

I am looking to instigate a button that becomes inactive after 60secs.
Ideally I would like a count down within the button. Have seen this, mostly on broker websites but would appreciate any help.

Did you want to hire someone to do this programming for you?

Was hoping it was something simple enough to do myself.

found this elsewhere on the site and have tried to adapt but not 100% sure what I'm doing

		<script language="JavaScript">
		var timerID = 0;
		var gseconds = 0;
		function UpdateTimer() {
		    gseconds += 1;
		    timerID = clearTimeout(timerID);
		    document.AXConfirm.theTime.value = gseconds;    
		    Start();
		}
		function Start() {
		    document.getElementById("ConfirmButton").disabled = true;
		    tStart    = new Date();
		    timerID  = setTimeout("UpdateTimer()", 10);
		}
		function Stop() {
		    document.getElementById("ConfirmButton").disabled = true;
		    if(timerID) {
		        clearTimeout(timerID);
		        timerID  = 0;
		    }
		}
		function Reset() {
		    document.getElementById("ConfirmButton").disabled = true;
		    document.AXConfirm.theTime.value = "0";
		    clearTimeout(timerID);
		    timerID  = 0;
		    gseconds = 0;
		}
		</script>

and the form

		<script>
		UpdateTimer();
		</script>
		<FORM action="index.cfm" name="AXConfirm">
		<input type="text" name="theTime">
		<input type="hidden" name="AllocatedTo" value="#EIN#">
		<input type="hidden" name="Allocate" value="#Generate.NewAX#">
		<input type="Button" name="Confirm" value="Confirm" style="color: White; background-color: Green;">
		&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
		<input type="Submit" name="Reject" value="Reject" style="color: White; background-color: Red;">
		</FORM>

I get an error on document.AXConfirm.theTime.value = gseconds; saying it is null or not an object
