Radio Form check if true

[tobeyt23]

Need help checking that either radio id=1 or id=2 or id=3 is checked. Each radio id may contain more than 1 option. Any ideas on how to does this?

I did this and it seems to work, does anyone see something wrong with it?

function radioEducationHasValue()
{
var found = false;

els = document.getElementsByName('hs_grade');
for(j=0;test = els[j];j++)
{
	if( test.checked )
	{
		found = true;
	}
}

els = document.getElementsByName('c_grade');
for(j=0;test = els[j];j++)
{
	if( test.checked )
	{
		found = true;	
	}
}

els = document.getElementsByName('post_grad');
for(j=0;test = els[j];j++)
{
	if( test.checked )
	{
		found = true;	
	}
}

if( !found )
{
	alert('Highest level compeleted must have one selected'); 

	return false;
}
return true;
}
