Font resizer help

[riskmod]

I am having issues with this:

$(document).ready(function(){
  var section = new Array('copy-content');
  section = section.join(',');
 
  // Reset Font Size
  var originalFontSize = $(section).css('font-size');
  $(".resetFont").click(function(){
    $(section).css('font-size', originalFontSize);
	return false;
  });
 
  // Increase Font Size
  $(".increaseFont").click(function(){
    var currentFontSize = $(section).css('font-size');
    var currentFontSizeNum = parseFloat(currentFontSize, 10);
    var newFontSize = currentFontSizeNum*1.2;
    if (newFontSize < 16) {
	$(section).css('font-size', newFontSize);
	}
    return false;
  });
 
  // Increase Font Size
  $(".increaseFont-more").click(function(){
    var currentFontSize = $(section).css('font-size');
    var currentFontSizeNum = parseFloat(currentFontSize, 10);
    var newFontSize = currentFontSizeNum*1.35;
    if (newFontSize < 18) {
	$(section).css('font-size', newFontSize);
	}
    return false;
  });
  
});

HTML

<li><a href="#" class="normal resetFont">A</a> | <a href="#" class="zoom-in increaseFont">A</a> | <a href="#" class="zoom-more increaseFont-more">A</a></li>

It works.....but when you click on increaseFont (good) and click after increaseFont-more, it wont function

...resetFont works (resets back to normal) ...
....but cannot go bigger with increaseFont-more and vice-versa if Im in increaseFont already.....only resetFont will work....what am I missing?

Thanks
