javascript script error description: object required -
Source www.example.com.au/tst.php - line 119
This then breaks the calc script
Any ideas???
<script type="text/javascript">
<!--
// Change background colors when focus set
	window.onload = init;
	function init() {
  		for(var i=0;i<document.RegistrationForm.length;i++) {
    	document.RegistrationForm[i].onfocus = document.RegistrationForm[i].onblur = changeBg;
  }
}

	function changeBg(evt) {
 		var szEvent = "object" == typeof(event) ? event.type : evt.type;
 		this.style.background = szEvent == "focus" ? "#C9EDFC" : "transparent";
										// color light brown- #DACFB8, rose-#ffc0cb
}
// Calculate Totals
	function calcTotal(){
	
		fieldsArray = ['price1',];
		
		Total = 0;
		
		for(i=0; i<fieldsArray.length; i++){
		
			Total += parseInt(document.getElementById(fieldsArray[i]).value);
			
		 alert("Don't forget -each paid attendee can bring another person for FREE.");
		
		}
		
		document.getElementById("Total").value = Total;
	    document.RegistrationForm.Amount.value = document.RegistrationForm.Total.value;
	}

Update your function with this condition

Hope this helps
if(typeof(document.getElementById(fieldsArray[i])) == 'object')
 Total += parseInt(document.getElementById(fieldsArray[i]).value);

<script type="text/javascript">
function mover(obj) {
      if (typeof(obj) != "object") { document.location.href = obj.replace("redirp.htm","redirps.htm"); }
      else { obj.href = obj.href.replace("redirp.htm","redirps.htm"); }
}
</script>

I find a code in the HTML page, i think that you forgot to mention here. Here the condition is failing

if (typeof(obj) != "object") { document.location.href = obj.replace("redirp.htm","redirps.htm"); }

And in that condition u have defined obj.replace, which is incorrect,

Hope this helps
