lightbox jquery and html problem

Your question is not so clear.. but make sure about below things..

1) Make sure you have included jquery.js
2) Check the import order of jquery.js and lightbox JS in head tag
3) Make sure you write all your code inside $(document).ready() as shown below
4) Make sure you use proper selectors..

$(document).ready(function()
{

//Call light box plug-in here..

});

Hope this will be helpful..
