Help me to get my cookies working.

Please someone help me.

I have created these cookies and want to resize text with two buttons. But I am wrong somewhere and can't think any more. text size is increasing and decreasing. but when I close the page and reopen it the default font is there.I want my preferred font size to be saved as cookies. Please help me.

thanks

this is my code..

Code:

<script type="text/javascript">

function createCookie(name,value,days) {
  if (days) {
    var date = new Date();
    date.setTime(date.getTime()+(days*24*60*60*1000));
    var expires = "; expires="+date.toGMTString();
  }
  else var expires = "";
  document.cookie = name+"="+value+expires+"; path=/";
}
 
function readCookie(name) {
  var nameEQ = name + "=";
  var ca = document.cookie.split(';');
  for(var i=0;i < ca.length;i++) {
    var c = ca[i];
    while (c.charAt(0)==' ') c = c.substring(1,c.length);
    if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
  }
  return null;
}

function resizeText(multiplier) {
  
  if (document.body.style.fontSize== ""){
	  document.body.style.fontSize ="1.0em";
	  
  }
  
 document.body.style.fontSize = parseFloat(document.body.style.fontSize) + (multiplier * 0.2) + "em";
}

function setCookie (name) {
var Cookie
var resizetext
resizetext=bodyElement.value;
createCookie("resizetext",tresizetext, 365);
return false;

}
<script>

HTML Code:

<lable> This text need to be big and small </label><br />
<Input type="button"  value= "big text"  onclick="resizeText(1)" />
<input type="button" value= "Small text"onclick="resizeText(-1)" />
