you could use a switch statement instead. Something like this:

Code:

var age = document.age.box.value;
switch(true){
  case(age <= 17):
    child_jump();
  case(age >= 18 && age <= 39):
    adult_jump();
  case(age >= 40):
    older_jump();
}

It's not tested but I think it should work.

Here's how I would do it - probably not the best way since I'll admit I'm no genius web programmer... Your description of the problem also doesn't cover the ages between 17 and 20? so this code does...

The html part:

<form name="mainForm" method="post" onSubmit="return formCheck()">
Please enter your age: <INPUT size="10" value=" " maxlength="3" name="age"><p>

please make a selection:<br />
<INPUT type="radio" name=selection> Web Search Engine <BR>
<INPUT type="radio" name=selection> Web Director<p>

<input name="" type="submit">
</form>

Then the javascript:

function formCheck() {

var age = document.mainForm.age.value;
if (document.tool.selection[0].checked==false && document.tool.selection[1].checked==false)
{
alert ("Please select a search tool!"); return false;
}
if (age > 0 && age < 120)
{
if ((age >0 && age <18) && document.tool.selection[0].checked=true) {
window.location = "http://www.askforkids.com/"; }
if ((age >0 && age <18) && document.tool.selection[1].checked=true) {
window.location = "http://kids.yahoo.com"; }
if ((age >17 && age <40) && document.tool.selection[0].checked=true) {
window.location = "http://altavista.com"; }
if ((age >17 && age <40) && document.tool.selection[1].checked=true) {
window.location = "http://dmoz.org"; }
if (age >40 && document.tool.selection[0].checked=true) {
window.location = "<over 40 url for selection 0>"; }
if (age >40 && document.tool.selection[1].checked=true) {
window.location = "<over 40 url for selection 1"; }
}
else
{
alert ("Please enter a valid age!");
return false;
}
}

hope that works for you...
