Hi juzwant2play,

There is no element with an id of 'totalcost'

. . . id="text_4" name="totalcost" . . .

Bob

Thanks for the reply. I am still getting the same error after adding the id tag.

<div class="form_item">
  <div class="form_element cf_textbox">
    <label class="cf_label" style="width: 150px;">Name</label>
    <input class="cf_inputbox" maxlength="150" size="30" title="" id="text_0" name="name1" type="text" onChange="updatesum()" />
  
  </div>
  <div class="cfclear"> </div>
</div>

<div class="form_item">
  <div class="form_element cf_textbox">
    <label class="cf_label" style="width: 150px;">Total Cost</label>
    <input class="cf_inputbox" maxlength="150" size="30" title="" id="totalcost" name="totalcost" type="text" />
  
  </div>
  <div class="cfclear"> </div>
</div>

function updatesum()
{
var c = 5;
document.ChronoContact_junk.totalcost.value = c;
}

Hi juzwant2play,

I think this is because you have the form twice in the page so the id isn't unique.

Bob

The form is only once on the page and the id is definitely unique. I copied the form code and javqascript code directly from the appropriate sections in chronoforms.

Hi juzwant2play,

I'm pretty certain that last time I looked the form was in teh page body and in a module at the bottom of the right hand column. The second copy and the error are both gone now as far as I can see.
