getRadioButtonValue question

[the4thmooncat]

I have been trying to modify an old function for a program I am using,
but I keep getting hung up on this:

if (radio[0].checked)
{
whatIs = true;
alert("attempting to return a true value");
}

The problem I get, using the debugger w/ firefox, is

Error ``TypeError: radio[0] has no properties''

What does this mean?

radio is this:

thaform.elements["a"];

where the form is 'thaform' and the radio buttons are named a.

Radio Buttons are in a class of there own when trying to access them.
