    rollno=(document.f1.t2.value);

    a=Number(document.f1.t3.value);
    b=Number(document.f1.t4.value);
    c=Number(document.f1.t5.value);
    d=Number(document.f1.t6.value);
    e=Number(document.f1.t7.value);

    if(a<=0 || a>100)
        alert("the value of marks 1 is invalid");
    if(b<=0 || b>100)
        alert("the value of marks 2 is invalid");
    if(c<=0 || c>100)
        alert("the value of marks 3 is invalid");
    if(d<=0 || d>100)
        alert("the value of marks 4 is invalid");
    if(e<=0 || e>100)
        alert("the value of marks 5 is invalid");
    total=a+b+c+d+e;
    t=document.f1.t8.value=total;
    per=total/5;
    p=document.f1.t9.value=per;

    if(per>=80)
        document.f1.t10.value="AA";
    else if(per>=70 && per<80)
        document.f1.t10.value="BB";
    else if(per>=60 && per<70)

{
    alert("please fill ALL Details");
}*/
if(document.f1.t3.value=="")
{
    document.f1.l3.value="enter password";
}
if(document.f1.t3.value!=document.f1.t4.value )
{
        document.f1.l3.value="invalid password";
}
var a=document.f1.t1.value;
document.f1.l1.value=testchar(a);
function testchar(m)
{
    var p="^[a-zA-Z]*$";
    var r=new RegExp(p);
    return r.test(m);
}
var b=document.f1.t2.value;
document.f1.l2.value=testnum(b);
function testnum(n)
{
    var s="^[0-9]*$";
    var v=new RegExp(s);
    return v.test(n);
}
var c=document.f1.t5.value;
document.f1.l5.value=testmail(c);
function testmail(l)
{
    var t="^[\\w-_\*]\*[\\w-_\.]\@[\\w]\.+[\\w]+[\\w]$";
    var x=new RegExp(t);
