@grifter7Aug 11.2009 — what youre trying to do is much more suited to javascript as PHP is server sided and theres no point in sending data to the server just to send it back again but if you must use [CODE]$youretextvariable=$_POST['document.abc.mylist.options[x].text'] only give the text value an id name [/CODE] the just echo this [CODE]$_GET['$youretextvariable'][/CODE]

@thraddashAug 11.2009 — You will need to actually "submit" the data back to your php server before you can refer to it. PHP does not have direct access to the DOM like you have it.

Use a submit button inside your <form> tags like:

[code=html]<input type="submit" value="Submit" />[/code]

Your data will end up in PHP as [B]$_GET['mylist'][/B] after it is submitted (because your method = "get").

Success!
