1. You're in the wrong forum. Post your question in the Web Development forum[^].
2. You're going to need to provide significantly more information that that if you expect anyone to be able to help you.
   
   • Create a minimal reproduction of the problem in JSFiddle[^] and post the link to it.
   • Tell us what version of Chrome you're using.
   • Include the full details of any errors.
   • Tell us what you've done to try to solve the problem.

• Every function or method should be prefaced with a short explanation of the algorithm that it implements or the task that it performs. Obviously, if the function is part of the public interface, this comment should take the form of an XML comment, which need not be repeated as a regular comment. You can also make a good case for attaching XML comments to every method. Indeed, I usually follow this practice in my own work, and I've seen it often in the work of others.
• Every class must begin with a short explanatory comment about its purpose. As is the case with methods, this can take the form of XML commenting.
• Every module must contain a change log, and you must be fastidious about adding a note, brief though it may be, every time you change it.
