Script to set the field value based on another field value

[Srikanth Gogineni]

Hi , 

please find the below scenario.

i have two fields A and B

i want to calculate(division) the field A value by 3 and round the value( for example if the value is 1.6 then 2 ), which needs to be assigned  to field B automatically.

here is the below code which i tried in field A configuration.

<script type="text/javascript">

function setAgreedSLADAYS() {

var sessioncounter = document.getElementById("customfield_14921");

sessioncounter = sessioncounter.value / 3;

var setagreedsladays = Math.round(sessioncounter);

document.getElementById("#customfield_13892").value = setagreedsladays;

}

sessioncounter.onchange=function(){

                setAgreedSLADAYS();

}

</script>

Can anyone help with the above script .Thanks in advance.
