[jQuery] Autocomplete - Problem accessing php file


Hi, I have the following script in my index.php file:
<script type="text/javascript">
    var options = {
        script:"get_labels.php?json=true&",
        varname:"input",
        minchars: 2,
        delay: 200,
        json:true,
        shownoresults:false,
        maxresults:15,
        timeout: 5000
    };
    var autocomplete_json = new bsn.AutoSuggest('labelinput', options);
</script>
This works fine as long as get_labels.php is located in the same
directory as index.php (root dir).
If I move the script to a folder called 'includes' and use the
following line: script:"includes/get_labels.php?json=true&", it
doesn't work.
I've tried different variations:
includes/get_labels.php?json=true&
/includes/get_labels.php?json=true&
../includes/get_labels.php?json=true&
What am I missing here?
Here's the plugin I'm using:
