UI Page dynamically calculated fields

[yundlu316]

I've created a form using a UI Page and would like some of the fields to dynamically change depending on what is entered in other fields.   For example if a user fills out field A with $100,000 and field B with $25,000, is it possible for field C to dynamically change to $125,000 (A+B) without submitting or reloading the page?   Would that be a client or processing script?

Thanks!

Change the deduct_3() function to this

function deduct_3(){

  var c = parseFloat($('deductions_adjustments_1').value) - parseFloat($('deductions_adjustments_2').value);

  if (c<= 0) {

  $('deductions_adjustments_3').value = 0;

  }

  else {

  $('deductions_adjustments_3').value =c;

  }

  }

I actually tried that first, but ServiceNow doesn't like that <= character

That is weird. Are you using this in client script section?

[yundlu316]

Nope, doing it in the HTML space like sum()

Use them in the client script section
