hi,
i'm looking validate script for....(document.insert.location1.checked == false) {
document.insert.student1.style.visibility = "hidden";
else {
document.insert.student1.style.visibility = "";

i want "student1" to be validated , only if i click on location1,

i tryed this script but , it checks "student1 ", before i click on "location1"

if(document.insert.location1.cheked!="")
{

document.insert.student1.value!="";
}

else { alert("student1 is not filled");}

Hi, welcome to the forum.

You need to put this script into an event, the event being theform being submitted.

First, make your code a function so it can be called at any time:

function check_loc1() {

if (document.insert.location1.checked) {

if (document.insert.student1.value=='') {
alert('Student1 is not filled');
return false;
}

return true;
}
return true;
}

In your <form> tag, add

onsubmit="return check_loc1();"

I haven't checked the code but you get the idea.
