Multiplying a form field by a specific number.

[mrsenos08]

How do I multiply a numerical form field by a specific number that is not in a form field?  I have absolutely no experience with Javascript.  Please HELP!

Let's say the first field is called Text1 and you want to multiply its value by 8 and show the result in Text2.

You can do it using this code as the custom calculation script of Text2:

event.value = Number(this.getField("Text1").valueAsString) * 8;

Great answer! Thanks. If you're willing to add more, I was needing to know:

What additional script would I need if I want Text2 to be left blank and ONLY want something to show in Text2 if Text1 has input?

Use this:

if(this.getField("Text1").valueAsString === "")
event.value = "";
else
event.value = Number(this.getField("Text1").valueAsString) * 8;

I was wondering if I could get a little help, cause I can't seem to figure this out.  I have a field where I will enter volume and need it to calculate the fee.  See attached screen shot.

Under the Simple Field Notation option in the Calculate tab of Fees enter this:

Volume * 0.03

Worked!! Thank you so much!  I didn't put any spaces between them and so it wasn't working, works like a charm now!  You rock!!
