I have four text fields in my form. When the user enters some value in any one of the fields, I want to disable other text fields. How can I get this to work in both Netscape and IE?

Ravi Verelly The below code works in Netscape and IE:
<html>
<head>
<title>form1</title>
<script language="JavaScript">
var flg = false;
function chk(){
var field = window.document.f1;
if (field.t1.value.length==0&&
field.t2.value.length==0&&
field.t3.value.length==0&&
field.t4.value.length==0)
flg=false;
}
function disablef(which){
chk();
if(flg&&which.value.length==0) which.blur();
else flg = true;
}
</script>
</head>
<body>
<form name="f1">
<input type="text" name="t1" onfocus="disablef(this);">
<input type="text" name="t2" onfocus="disablef(this);">
<input type="text" name="t3" onfocus="disablef(this);">
<input type="text" name="t4" onfocus="disablef(this);">
</form>
</body>
