    I have a form, which can have 0 or more checkboxes. When there are more than one the array attribut of the checkboxes work fine, when there is only one it doesnt. Can anyone explain why.

    I know its possible to have an array with only one element (in some languages, it might be different for javascript) so this is really doing my head in.

    please please please jim can you fix it for me to sleep in peace.

    Yeah you can have an array with only one element, are you looking at element[1] or element[0]?

    You can also test like this: 
    var checkBoxes = document.myform.checkboxes;

if (checkBoxes[1])   // there are at least two elements
{
   for (i =0; i < checkBoxes.length; i++)
   {
      //whatever
   }
}
else
{
   if (checkBoxes[0].checked)
   {
      // only one, and it's checked
   }
}
