Removing text fields

If the user changes the number of text fields, we must remove the existing label and value fields before we recreate the new fields. This is handled by the function removeTextFields, shown below.

function removeTextFields() {

   for (var i=0; i < 10; i++) {

      if (this["ChartLabel"+i]) {

         this["ChartLabel"+i].removeTextField();

      }

      if (this["ChartValue"+i]) {

         this["ChartValue"+i].removeTextField();

      }

   }

}

This function tests whether the text field exists and if so, removes it.
