JavaScript

I have this
------------------------------------------

<form name = "Myform">
<select name = "S[1]">
<option value="1">orange
<option value="2">red
</select>
</form>

---------------------------------------
I am using the S[1] because I am passing it off to a PHP script than handles all the "S" selects as an array
---------------------------------------
how can I use javascript to check to value of the select

<Script= "JavaScript">
alert(document.Myform.S[1].value)
</script>

doesn't work
"document.Myform.S.1 is not an object"

Perhaps this will give you an idea how to handle JavaScript objects.

Code:

<html>
<head>
<title></title>

<script language=javascript>
<!--

function button_onclick() {
  alert( document.myform.s.value )
}

//-->
</script>

</head>
<body>

<form name="myform">
  <select name="s"> 
    <option value="1">orange
    <option value="2">red
  </select>
  <input type="button" value="button" id="button" name="button"  language=javascript onclick="return button_onclick()">
</form>

</body>
</html>

all objects are arrays in html

Code:

<html>
<Script language="JavaScript">
function x(){ 
alert(document.Myform.S[1].value) 
}
</script> 

<body>

<form name = "Myform"> 
<select name = "S"> <!-- this select is S[0] -->
<option value="1">orange 
<option value="2">red 
</select> 

<select name = "S"> <!-- this select is S[1] -->
<option value="1">green 
<option value="2">purple
</select> 
<input type='button' onclick='x()'
</form> 

</body>
</html>

thanks,

I get it but its going to give me a couple of problems.
But I think I will be able to work around it by making my code nice and messy

I need to assign the array values my self
it might not be 0,1,2,3

but it needs to be

445,743,162

but again I can work around this by adding a hidden field that holds the real values for the arrays, so when it is passed off to the script the script knows whats up

S[0]=s[445]
etc

Can't get it to work

how do I read the selects in my PHP script

echo S[0];
echo S[1];

I am only receiving the last one
