I'll start you on your way... but before I do you must know that if you post a question like that, you are most likely not going to get many responses. There are too many errors, and you can't expect someone to go through your entire code to debug it for you. If you want help with a specific error, then post the error, the relevant code, and let us know what you have done so far to try to fix it.
A community like this exists to help if you get stumped, but not to do your job for you. Part of your job as a website developer is debugging -- lots and lots of it!
Ok, that said...
Most of your warnings are not fatal. My guess is that you have error_reporting = E_ALL in your php.ini file. If you have access and authority to change it, change it to error_reporting = E_ALL & ~E_NOTICE... that way you won't get notices (non-fatal warnings). That may not fix all of your problems, but it will take care of the warnings you are getting by using uninitialized variables (like $radio).
