I try to create a relation/connexion beetwen 2 selectbox

```
<form id="creation" name="creation">
<select name="select01" id="select01">
     <option value="01">01</option>
     <option value="02">02</option>
     <option value="03">03</option>
</select>

<select name="select02" id="select02">
     <option value="aa">aa</option>
     <option value="bb">bb</option>
     <option value="cc">cc</option>
</select>
</form>

```

I want that my selectbox **select02** be disabled at the begening, and when i click on **value02** or **value03**, we enable it, and when we click on **value01**, disable it.

There is my code js for the moment. I try to adapt it from an other function (radiobutton enabling a selectbox) but it doesn't seem to work. My list is disable at the beging, but the onclick is not working ...

Some body can help me?

```
var oui = document.creation.select01[0];

document.getElementById("select02").disabled=true;
oui.onclick = function() {
document.getElementById("select02").disabled=false;
}

```

Ok, so NOW, i'm with this code:

```
<script>
var oui = document.select01;
document.getElementById("select02" ).disabled=true;
oui.onchange = function(){
document.getElementById("select02" ).disabled=false;
}
</script>

```

I change the value of my selec01, then my select02 is now enable .. but how can I target only 2 options of my select01 ?
