Access objContent value using Javascript

Hi there

I have a page with multiple uses of the FCK Editor object. When a form on this page is submitted I run a script to set the values of various hidden fields. I need the value of the fck object but cant seem to retrieve it using Javascript. I am trying:

function submitForm(i) {
document.submitForm.questionText.value = document.forms(i).fckObject.value
}
Any help or advice most appreciated.
