hi everyone,
using the form reset button it only resets to the values that the page loads with..

Is it possible to clear all values within the form, even though its prepopulated with session data.

i.e. set all text fields to '' and set all radios to empty?  
thanks

There is no predefined function supplied by javascript to clear all the values.
You have to do it explicitly; something like this inside the script:
for(i=0;i<document.forms[0].elements.length; i++){
  ele = document.forms[0].elements[i];
  if(ele.type == "text" || (ele.type == "textarea" ){
     ele.value == "";
 }else if(ele.type == "radio") {
     if(ele.length){
         for(j=0; j<ele.length;j++){
             ele[j].checked = false;
         }
     }else{
       ele.checked = false;
     }
     //Continue checking for all the other element types like check box, hidden etc
 }
 

}
