Require javascript formula to determine percentage in Acrobat DC Pro form

[Frank Sobolewski]

I have a form that requires percentage to be calculated using values input by person filling form.

Text4.0 is no. of attendees

Text4.1 is no. of Employees

Text 4.2 is the percentage calculation

For the case of the number of employees being non-zero, I would divide the number of attendees by the number of employees. I would set the field format to the percentage display format and specify the number of decimal places to display. Acrobat JavaScript considers division by zero to result in Not a Number or NaN. One can only use the Custom JavaScript calculation method.

// get computational  values;

var nAttendees = this.getField("Text4.0").value;
var nEmployees = this.getField("Text4.1").value;

event.value = 0;

// clear result field;

if(nEmployees != 0){

// compute if divisor not zero;
event.value = nAttendees / nEmployees
}

That works great! Thanks for the information. 

This may be ao ongoing requirement for my business. Do you have a suggestion as to how I can either

a) learn how to do this

b) contract someone to do this. 

Thanks again!!!
