Google Map And Java Pulling my hair out over this

[Echo_of_thunder 1]

Okay I am pulling all my hair out over this, and have been for weeks now. I am not too bright when it comes to Java scripts and all this, but I have been working on a google map. my map okay got it all centered on the usa and the controls. thing is I would like adding a national weather radar overlay to it. I have searched google and every group they have on this matter. Everyone has said read the help files or go there or here or anyplace, and not really been any help what so ever. I am at a total loss of how. I have even tried to view source of radars thinking maybe it was a KMZ file I needed to add, and I do think it is but where do I add it and how? As I said Java is not my thing at all. Just drinking it in the morning.

If anyone here is willing to help me out and make it very simple to understand I really would be greatful

Thank you
