<form action="https://*****.php" method="post" id="mainform" onsubmit="validate();">
      
       <input name="subject" type="hidden" value="EirGrid Annual Customer Conference 2007- Online Booking" />

       <input name="template" 
type="hidden" id="template" value="emailtemplate18.htm" />

Oops sorry, the code tags have got a bit messed up. I hope you can still read it properly.

It probably is running, but it is not preventing your form from being submitted. You need to return a value to the onsubmit event, in terms of: 

onsubmit="return validate();"

Then, returning false (

return false;
) from your validate function will prevent the form from being submitted.

Hi, I'm still not getting anywhere with this. I've attached a stripped down the code so its easier to read and have attached it again below. I've also uploaded the webpage go you can see it up and running on the following link [planetipod.co.uk]. As you will see I have the other basic validation up and running but I don't know where to start with the checkbox validation.

Any suggestions on code? 


<script language="JavaScript" type="text/JavaScript">
function validate() {
var message='';
var count=0;
formName=mainform.Name.value;
formCompany=mainform.Company.value;
formTelephone=mainform.Telephone.value;
formEmail=mainform.mailfrom.value;
if (formName=='') {
count=count + 1;
message=(message + count +". NAME :\t\tName Missing\n");
event.returnValue=false;
}
if (formCompany=='') {
count=count + 1;
message=(message + count +". ORGANISATION :\tOrganisation Missing \n");
event.returnValue=false;
}
if (formTelephone=='') {
count=count + 1;
message=(message + count +". TELEPHONE :\t\tTelephone No. Missing \n");
event.returnValue=false;
}
if (formEmail=='') {
count=count + 1;
message=(message + count +". EMAIL :\t\tEmail Address Missing\n");
event.returnValue=false;
}
if (count>0){
alert("You missed "+ count +" fields on this registration form.\nPlease fill in the following fields: \n\n"+ message +"\n Click OK to correct these errors");}
}
</SCRIPT>

Form Code below: 


<form action="#" method="post" id="mainform" onsubmit="validate();">
