Newbie variable question

Newbie variable question

Howdy all,

I'm a self confessed newbie to jQuery and the world of javascript and for the life of me I can't find why I keep getting a 'Cannot assign to a function result' error.

Basically, I have 2 <a> tags that act like buttons with a <span> tag between them that displays a number. When the user clicks on the right arrow I want the number that is displayed in the <span> tag to increment by one, and when they click on the right arrow I want it go back one number. Sounds simple enough, but apparently not to a newbie. I need to rotate between the number 1 & 50 (both forwards and backwards), so if they are on 1 and click back one, it should display 49. I'll be developing this script further to pull in ajax content based on the number displayed but one step at a time

Thanks in advance btw....

Here's what I've got so far.....

  1. $(document).ready(function () {
        var CurrentCount = $('#Top50Count').html()
        var Increment = 1
        var NextCount = parseInt(CurrentCount) + parseInt(Increment)
        var PreviousCount = parseInt(CurrentCount) - parseInt(Increment)
        $('#Top50NavNext').click(function (e) {
            $('#Top50Count').html() = NextCount;
            e.preventDefault();
        }
    );
    }
    );
