Looping through checkboxes

[smellykat]

I need a function that will loop through the checkboxes I have on my form - all with the same name - and check that at least one box is checked. If not, alert them that it is required.
Any ideas?

try

function NoneSelected(objCheckbox)
{
	var Result = true;
	for(var i=0;i<objCheckbox.length;i++)
	{
		if (objCheckbox[i].checked)
		{
			Result = false;
			break;
		}
	}
	return Result;
} //NoneSelected

call it like NoneSelected(document.formName.checkboxName)
