Adobe Form Checkbox Condition Question

You can use this code as the Mouse Up event of the first check-box:

var subFields = ["500 Cab Design Options - Acrylic", "500 Cab Design Options - Rail Wall", "500 Cab Design Options - Frame"];
if (event.target.valueAsString=="Off") {
	for (var i in subFields) this.getField(subFields[i]).readonly = true;
	this.resetForm(subFields);
} else {
	for (var i in subFields) this.getField(subFields[i]).readonly = false;
}

Edited: Small mistakes fixed in the code

What is the export value of Cab Style#5?
