Jon,

Tried your method and still got:
*Error: Object doesn't support this property or method.
Code: 0*

I'm no JavaScript expert, but I could maybe suggest an alternate method:
use document.getElementById() or document.getElementsByName()

AFAIK, the direct document.xyz doesn't work exactly the same way accross
browsers (if at all).

e.g. (WARNING! TOTALLY UNTESTED CODE!)

function checkInputValue(item,onError) {
   if (item = document.getElementsByName(item)[0]) {
      if (item.value != "") {
         return(true);
      }
   }
   alert(onError);
   item.focus();
   return(false);
}

function checkForm() {
   elements = new Array('cc_phone_number');
   errors = new Array('Please enter a phone number');

   for (i=0;i<elements.length;i++) {
       if (!checkInputValue(elements[i],errors[i])) {
           return(false);
       }
   }

   document.getElementsByName('inputForm')[0].submit();
}
