What should be a simple 'button' script

Question

Too old, too many hours working on this and too tight a deadline. This should be a simple script, but I'm getting nowhere fast!
User enters a dollar amount into a field called 'Pay', clicks one of four radio buttons called 'Frequency' labeled 'Weekly', 'By-weekly', 'Monthly' and 'Annual'. Based on button pressed, a field called 'Annual' is updated to reflect the results of:
Weekly = Pay * 52
Bi-weekly = Pay * 26
Monthly = Pay * 12
Annual = Pay * 1
Eventually, this form will be distributed throughout our entire organization, with completed forms being emailed to a central office. As a result, I'm working in LiveCycleES and Java, both of which I'm a novice with.
Any assistance from this forum is greatly appreciated. Even a link to a working example of this process that I could decipher on my own would be a great help.
Thanks so much.

Answer 1

For a radio button group called 'frequency' where the value binding is
1 - weekly
2 - bi-weekly
3 - monthly
4 - annual
you could add the following client-side JavaScript to the 'frequency' change event.
var frequency = form1.subform1.frequency.rawValue;
switch (frequency) {
case "1":
form1.subform1.annual.rawValue = form1.subform1.pay.rawValue * 52;
break;
case "2":
form1.subform1.annual.rawValue = form1.subform1.pay.rawValue * 26;
break;
case "3":
form1.subform1.annual.rawValue = form1.subform1.pay.rawValue * 12;
break;
case "4":
form1.subform1.annual.rawValue = form1.subform1.pay.rawValue * 1;
break;
default:
break;
