Scrolling Cart Script for a particular catalog item

[Cupcake]

Hi am trying this script for my catalog item that I got from the user community and I keep getting an error. Can someone take a look please?

Here is the link where I got the code from: Scrolling Cart for Service Request - Oslova Networks

Thank you,

Karen

var adder;
var adderFound = 'false';
var cartContent;
var cartContentFound = 'false';


function onLoad()
{


       adder = gel('adder');
       if (adder)
       {
               adder.style.position = "relative";
               adderFound = 'true';
       }


       cartContent = gel('sc_cart_contents');
       if (cartContent)
       {
               cartContent.style.position = "relative";
               cartContentFound = 'true';
       }


       window.onscroll = function()
       {
               var y = 12;


               if (typeof window.pageYOffset != 'undefined')
                       y = window.pageYOffset;
               else if (typeof document.documentElement.scrollTop != 'undefined' && document.documentElement.scrollTop > 0)
                       y = document.documentElement.scrollTop;
               else if (typeof document.body.scrollTop != 'undefined')
                       y = document.body.scrollTop;


               if (y > 60)
               {
                       if (adderFound == 'true')
                               adder.style.top = y - 60 + 'px';


                       if (cartContentFound == 'true')
                               cartContent.style.top = y - 60 + 'px';
               }
               else
               {
                       if (adderFound == 'true')
                               adder.style.top = 0 + 'px';


                       if (cartContentFound == 'true')
                               cartContent.style.top = 0 + 'px';
               }
       }
}

Thank you David for the correcting the code. This is most helpful.

No more errors, but when I tried it out the "Order Now" button is NOT scrolling when the cart scrolls.

Re-examining my code, you may wish to make:

var adder;
var adderFound = 'false';
var cartContent;
var cartContentFound = 'false';

function onLoad()
{
         adder = gel('adder');

Into:

var adder;
var cartContent;
function onLoad()
{
       var adderFound = 'false';
       var cartContentFound = 'false';
       adder = gel('adder');

Now, to address the "already defined" issue in the catch statements, you can use the first piece of code I gave you and change all your catch(e) lines to catch(e1), catch(e2), catch(e3), etc...   giving each catch parameter it's own namespace.   This is a known issue with JavaScript's try/catch, as noted here:   http://stackoverflow.com/questions/6100230/javascript-catch-parameter-already-defined
