Hi everyone! I have some script which is working in firefox and chrome but in IE 8 I get this error:

$.Autocompleter.defaults = {
    inputClass: "ac_input",
    resultsClass: "ac_results",
    loadingClass: "ac_loading",
    minChars: 1,
    delay: 400,
    matchCase: false,
    matchSubset: true,
    matchContains: false,
    cacheLength: 10,
    max: 100,
    mustMatch: false,
    extraParams: {},
    selectFirst: true,
//the following line throws the error, read down for error message
    formatItem: function(row) { return row[0]; },
    formatMatch: null,
    autoFill: false,
    width: 0,
    multiple: false,
    multipleSeparator: ", ",
    highlight: function(value, term) {
        return value.replace(new RegExp("(?![^&;]+;)(?!<[^<>])(" + term.replace(/([\^\$()[]{}*.+\?\|\])/gi, "\$1") + ")(?![^<>]>)(?![^&;]+;)", "gi"), "$1");
    },
    scroll: true,
    scrollHeight: 180
};

can I perhaps change the the row[0] to something? This is found in jquery.autocomplete.js and it reads the same in firefox and doesn't cause the error, so i don't really want to change this if at all possible.

any advice would help thanks!
