How Do You Change A Numeric Field To Blank When Zero?

Question

I'm using Adobe Acrobat 6.0 Professional, version 6.0.6.
Can anyone help me with the code to change a numeric field to blank, when "0.00"?

"no success" does not provide much to go on.
With your scripts, I get the concatenation of the sting values, so one has to force JavaScript to convert strings to numbers.
Make sure your field names are exact including case.
Make sure the calculation order is correct.
The following scripts all work:
var fa = 1 * this.getField("FeeN01").value;
var fb = 1 * this.getField("FeeN02").value;
var fc = 1 * this.getField("FeeN03").value;
event.value = fa + fb + fc;
if ((event.value == 0)) {
event.value = ""
// or
var fa = this.getField("FeeN01").value / 1;
var fb = this.getField("FeeN02").value / 1;
var fc = this.getField("FeeN03").value / 1;
event.value = fa + fb + fc;
if ((event.value == 0)) {
event.value = ""
// or
var fa = Number(this.getField("FeeN01").value);
var fb = Number(this.getField("FeeN02").value);
var fc = Number(this.getField("FeeN03").value);
event.value = fa + fb + fc;
if ((event.value == 0)) {
event.value = ""
The "sum of" also works with the "Custom validation script" of:
if (event.value == 0) event.value = "";
