I know this is an extremely basic question, but I just couldn't find anything useful on the internet. I have 2 input boxes and I want calculate that input and put the result in output using submit button and navigating by form id.

<script>

function Calculate()

{



  var resources = GetFieldValue( Resources );

  var minutes = GetFieldValue( Minutes ); 

  var permin = parseFloat(resources) / 60;

  var result = parseFloat(permin) * parseFloat(minutes);

</script>
