Array issue

    I am sure this is quite basic but from an obscure angle.

    I am controlling a relay board using HTML and it reports the status of the relay using a range of replies. The page is served from the device using an extremely small and basic web server.

    To display this reply in the document served by the device (NETIOM) I only have to insert %61 for relay 1, %61 for relay 2 etc.

    I want to use this response to manipulate the page within IE by testing the state of relays and changing the background colour accordingly. However, I cannot seem to find a way to wedge this into my Javascript. Ideally I want the valuse to be held in an array to be tested later in the script. I did try the following and (obviously) it failed. If I can fix this issue I intend to roll this out to multiple identical devices performing very similar roles, hence using naming arrays which can quickly modify which device I am writing for.

    Any ideas about how to acheive this? I realise there are shortcomings with not using CSS etc but this is only for use by me and two other people internally on IE6/7, compatability outside this range is irrelevant.

    Oh, lastly this page is only one element of a larger framed web page.

    Any help would be appreciated.:)

    Thanks

    Put your array values in quotes.
