Help with java script calculations in fillable form in DC

[Jennifer25775528aitl]

I'm trying to add a calculation in a fillable form for simple interest to make things easier on the end user. Below is my latest attempt to get this to work. It continues to give a syntax error. Where am I going wrong?

Interest Earned = ( this.getField("Ave Bal").value *0.001).value

Is this supposed to be the calculation script for "Interest Earned"? If so, use this:

event.value = Number(this.getField("Ave Bal").value) * 0.001;

Please read this simple guide on how to write calculation scripts.
