Get Label Text From Checkbox (IE8)

I've been trying everything I can to get the label text of this checkbox and nothing is working. I can get the length of the selectManyCheckbox object and I can tell if a checkbox is checked, I can even get the value of the checkbox. But I can't get the label text.
.innerText returns an empty string
.innerHtml returns an undefined
.textContent returns undefined

This is the function I'm using. I need the LABEL text NOT the value! I'm using IE8
function myfunction2(){
var x = document.getElementById('recipeForm:smc2').getElementsByTagName('input');
alert(x.length+"boxes.
first box is "+(x[0].checked?'ticked':'unticked'));
alert(x[0].innerText);
alert(x[0].textHtml);
alert(x[0].textContent);
}
