uncaught typeerror undefined is not a function

jQuery(document).ready(function(){
jQuery(“.a-product-image”).colorbox({transition: ‘elastic’, initialWidth: 200, maxWidth: ‘90%’, maxHeight: ‘90%’, rel:’gal’});
});

This gives me an “uncaught typeerror: undefined is not a function”

I have included jQuery and after that colorbox. Any idea what is causing this?
