Conditional text

Question

I have several combo boxes with the same 3 items in each.
one of the items = "fail"
If  one or more combo box's = "fail" I want to pass the value to a text box and for it to remain there until none of the combo box's value = "fail".
I have tried to fix it by adding a second (hiddden) text box where only the item "fail"  value is added. The only problem is that if the item "fail is removed from  all  the combo boxes the value needs to be removed from the text box. How do I do that , am i on the right track?
Cheers for any help

For the custom calculation for the text field:
// array of field names to check
var aFields = ("CheckBox1", "CheckBox2", "CheckBox3");
// clear the field's value
event.value = '';
// loop through the check boxes and test for 'Failed"
for(i = 0; i < aFields.length; i++) {
   if(this.getField( aFields[i] ).value == "Failed") {
      // set event value to "{Failed"
      event.value = "Failed";
      } // end match field
   } // end loop of check boxes
