The script created in step 10 defines a variable f, which corresponds to the value of the
ValueA field, and another variable g, which corresponds to the value of the ValueB field. The
script then defines an event that calculates the difference between the values of the two
variables.This calculation is automatically displayed in the ResultsC field.
To divide the value for variable f by variable g, replace the script text in step 10 with the
following text:
var f = this.getField("ValueA");
var g = this.getField("ValueB");
event.value = f.value / g.value;
To multiply the value for variable f by variable g, type in the following script (in its exact
format):
var f = this.getField("ValueA");
var g = this.getField("ValueB");
event.value = f.value * g.value;
12 Click OK in the Field Properties window.
