OOooops,

I guess I should have added some of the code so you can see what I'm up against, sorry..

createCatalogDB();
if (total_ordered > 0) {
  document.writeln('<a href=shoppingcart.html>' + 'view shopping cart</a>');
}
else {
  document.writeln('Shopping cart is empty.');
}
document.writeln('<hr>' + '<br />');
 
for (var n = 0; n < catalogDB.length; n++)
{
  document.writeln('<table width="800" align="center">');
  document.writeln('<tr><th align="left" height="300" width="195">' +
          '<img src="' + catalogDB[n].imageSrc + '" border="1" ' +
          'alt="' + catalogDB[n].item + ' "</th>');
  document.writeln('<td><b>' + catalogDB[n].item + '</b> </b><br />');
  document.writeln('Catalog Number: ' + catalogDB[n].number + '<br />');
  document.writeln('<i>'+ 'Price $' + catalogDB[n].price + '.00' + '</i><br />');
  document.writeln('<a href="javascript:addCatalog(\'' +
          catalogDB[n].number + '\')">' +  'Purchase</a><br />'); 
  document.write('</td></tr></table>');
 

I have to add a popup link to this script so that when the item gets clicked on they can see a larger image and details in the popup..

Hopefully someone will be able to help out here..thanks all
