Unless you are not also coding in HTML and javascript, using those others would only be a problem if somehow, in the course of your implementation, you have gotten a path or paths wrong or have caused markup/scripts to appear out of sequence in the served source code.
Use your browser's 'view source' to see how the page is being served. If it doesn't conform to the example's source code, you must track down what you did to cause that.
If you want more help, we would need a link to a live demo of the problem, and perhaps the source code of your server side pages involved in this.
Please post a link to the page on your site that contains the problematic code so we can check it out.
