javascript calcutation help for one with no knowledge of javacript

Question

HELP! I want to do 2 simple calculations in text fields in my form. But I have never done any javascript programming in my life and have no clue how to write the code. All I know how to do is click on the field, then properties, then the Calculate tab, the custom calculation script button, then edit. Can someone tell me what to put in the Create and Edit JavaScripts field, please? Thanks in advance for your help.

1. PRICE EA = (PKG PRICE + SH COST)/(QTY/PKG)

2. LINE TOTAL = QTY * (PKG PRICE + SH COST)

I recommend reading this tutorial: https://acrobatusers.com/tutorials/how-to-do-not-so-simple-form-calculations

For "PRICE EA" you can use this code:

var v1 = Number(this.getField("PKG PRICE").valueAsString);
var v2 = Number(this.getField("SH COST").valueAsString);
var v3 = Number(this.getField("QTY").valueAsString);
var v4 = Number(this.getField("PKG").valueAsString);

if (v3==0 || v4==0) event.value = ""; // division by zero is not allowed
else event.value = (v1+v2)/(v3/v4);

For "LINE TOTAL" you can use this code:

var v1 = Number(this.getField("QTY").valueAsString);
var v2 = Number(this.getField("PKG PRICE").valueAsString);
var v3 = Number(this.getField("SH COST").valueAsString);

event.value = v1*(v2+v3);
