Javascript errors in Mozila

[cwj]

I have a form that I am validating. The script works fine in IE, but
Mozilla is a defferent story.

Here is the section that is giving me problems.

// Preferred contact method
if ((document.cont act_form["contact_prefer "][0].checked == false)
&& (document.conta ct_form["contact_prefer "][1].checked == false)) {
field_errors = field_errors+"P referred contact method -
Please tells us how you would prefer to be contacted \n";
errors++;

The Mozilla error reads:
document.contac t_form["contact_prefer "][0] has no properties.

Anyone know the answer to this one?

Thanks

Re: Javascript errors in Mozila

Thanks for your help gang.

Ended up I didn't need to validate those radio buttons after all, but
you gave me lots to go on for the next time around.

Thanks for all the quick responses. Hope I can be as helpful one day.

You have not shown the required snippets of the underlying markup, so
guessing is all what is possible. Let us assume that "contact_fo rm"
is the name (i.e. the value of the "name" attribute) of a "form" element
and you try to access the first form control named "contact_prefer ".
The proper, because standardized, way to access that control is

document.forms["contact_fo rm"].elements["contact_prefer "][0]

This works, of course, only if there is more than one control of that
name, otherwise there is no HTMLCollection object from which to retrieve
the first item.
