Hi,

I have the following form which function without any problems as a plain HTML form:

<script type="text/javascript">
function totalprice()
{
var a = document.form1.lengte.value
var b = document.form1.diepte.value

var oppervlakte = (a * b)/100
 
var c = oppervlakte*5.50
 
document.form1.total.value = c
}
</script>
 
 
</head>
<body>
<form action="bereken.php" method="post" name="form1">
  <p>Lengte in centimeter:
  <input name="lengte" id="lengte" onblur="totalprice();" value="100" size="10">
  </p>
  <p>Diepte in centimeter: 
    <input name="diepte" id="diepte" onblur="totalprice();" value="50" size="10"><br>
  </p>
  <p>Uw prijs:
    <input name="total" id="total" size="10" readonly=true><br>
    
  </p>
</form>

When I try to implement this in Chronoforms (by splitting the form html and code) I get the following error:

Message: 'document.form1.lengte' is empty or not an object

In Chronoforms the form is also called form1.

Can you give me any tips on how to solve this?
Thanks,

Hi KootJoo,

If you check the page HTML with View Source you'll find that the form is no longer called 'form1' but 'ChronoContact_form1'
