Listbox value in the textbox

Hello all
I have one list box ans text box on my site, lik this:

Expand|Select|Wrap|Line Numbers

 <select name="lstScript">

<option>Javascript</option>

<option>VBscript</option>

<option>PHP</option>

<option>Actionscript</option>

<option>Other</option>

</select>
 
<input type="text" id="txtScript" readonly="yes" />

When I click on the item 1 from the list box (lstScript) I'de like to see the value "Javascript" in the text box so I add a script function:

Expand|Select|Wrap|Line Numbers

  <select name="lstScript"   onchange="txtScript.value = lstScript.vlaue" >

  ...

  </select>

But it doens't work like this, any suggestion or experience to solve this pleas?

do not start identifiers with digits- 1stvalue is invalid.
You also need to set values to read them.
