[takeiteasy]

Sorry! i'm new to Javascript here and would like somebody to explain to me on how the code below works...[code]
<script language="JavaScript">
<!--
function SynchMoves(which) {
  var ml=document.form1;
  if(which==1) {
      ml.select2.selectedIndex=ml.select1.selectedIndex;
  }
  else {
      ml.select1.selectedIndex=ml.select2.selectedIndex;
  }
    }


function submitForm(val){
  document.form1.actionType.value=val;
  document.form1.submit();
}

function valbutton(val1){
   var atleastOneRadioSelected=false;
   //f = document.forms[0];
   f=document.form1;

   f1 = document.forms[1];
   //alert("The value in the 2nd form is"+f.text.value);
   for(i=0;i<f.length;i++){
       var e = f.elements[i];
       if(e.type=="checkbox" && e.checked){
           atleastOneRadioSelected=true;
       }
   }
   //alert("Atleast value "+atleastOneRadioSelected);
   if(!atleastOneRadioSelected) {
       alert("You must select a record to " + val1);
   }else{
       //alert("Do you really want to " +val1+"?");
       var ans1 = "Do you really want to " +val1+"?";
       ans = confirm(ans1);

     if (ans == true) {
        f.actionType.value=val1;
        f.submit();
      } else {
         return false;
     }
         //f.actionType.value=val1;
         //f.submit();
   }
}

I'm currently doing a PHP project whereby i have 3 buttons, Edit, Delete and Save in my index form.
I have checkbox for checking and when i checked the checkbox, press edit button, it will appear the edit page where it will display the initial records ready for edit.
For the delete, i check the box, press delete and it will prompt me to confirm delete...same goes for the save button.
But now my problem is when i clicked on the edit button for example, it does not produce the edit.php page with all the nesscary details for edit.So how do i go about this?can someone help?! TIA!

[code]
  <input type='checkbox' name='checkbox' value='$empRef'>
   </td>
    <td width='60' bgcolor='$row_color' nowrap>
    $empRef
