HELP needed please…

Dear Experts,

This is regards to [COLOR=”Red”]“geometric properties of a triangle”[/COLOR]. I’m using this code:

/* This script and many more are available free online at

Created by: Sandeep Gangadharan | [url]http://sivamdesign.com/scripts/[/url] */
function getProp() {
var A = document.prop.A.value;
var B = document.prop.B.value;
var C = document.prop.C.value;
var S = (parseInt(A) + parseInt(? + parseInt(C)) / 2;
var Z = parseInt((A*A)+(B*?+(C*C))/parseInt(2*A*?;

document.prop.area.value = Math.round(Math.sqrt(S*(S+A)*(S+?*(S+C)) * 5) / 1;
document.prop.lic.value = Math.round(Math.PI * (document.prop.area.value/S) * (document.prop.area.value/S) * 5) / 1;
document.prop.sic.value = Math.round(Math.PI * ((A*B*C)/(4*(document.prop.area.value))) * ((A*B*C)/(4*(document.prop.area.value))) * 5) / 1;
document.prop.ang.value = Math.round(Math.atan(Math.sqrt((1/(Z * Z))+1)) * (180/Math.PI) * 10000) / 10000;
}

But the answer is I’m getting is wrong… My lecturer gave me this:

1 st No. 3177
2 nd No. 8367
3 rd No. 7005
Angle between A and B: 76149286

???Kindly assist me… Very urgent…???
