Question

In code below, I expect variable counter to incement by 1 on each repetition, but it remains zero.

var count = 0;
var marqueeText = new Array("Some text goes here",
                            "A bit more verbose text goes here.",
                            "Some more verbose <a href='xxx'>text</a> goes <a href='xxx'>here</a> with some <a href='xxx'>links</a>."
                            );

function fnShowMarquee(count){  
// console.log(count + "-" + marqueeText.length );
        if (count > marqueeText.length){
            count = 0;      
        }
        else{           
            count++;
        }
        $('#marquee_box span').html(marqueeText[count]);

            // do some stuff, then wait 4 seconds and call function again

        setTimeout ("fnShowMarquee(count)", 4000);
}


$(document).ready(function() {
    fnShowMarquee(0);
});

I’d try using count explicitly:

setTimeout (function() { fnShowMarquee(count); }, 4000);
