javascript populate fields based on date

OK, then you can use this code as the custom calculation script of the "Qtr" field:

var dateOfInspString = this.getField("DateOfInsp").valueAsString;
if (dateOfInspString=="") {
	event.value = "";
	this.getField("FY").value = "";
} else {
	var dateOfInsp = util.scand("mm-dd-yyyy", dateOfInspString);
	if (dateOfInsp.getMonth()>=9) {
		event.value = "4";
		this.getField("FY").value = dateOfInsp.getFullYear()+1;
	} else {
		if (dateOfInsp.getMonth()>=6) event.value = "3";
		else if (dateOfInsp.getMonth()>=3) event.value = "2";
		else event.value = "1";
		this.getField("FY").value = dateOfInsp.getFullYear();
	}
}
