Hi, I still learning JavaScript, so take this with the proper caution.
"checked" is a boolean value (true or false), so you should use an "if"
statment; something like this:
for ( i = 0; i < document.forms[0].elements['somename[]'].length; i++ )
{
if ( document.forms[0].elements['somename[]'][i].checked == true)
alert ( document.forms[0].elements['somename[]'][i]);
}
