Can somebody tell me where I'm going wrong with "callback_" ?

Thanks for your help dude.
I think I kinda get how it works now, but I still cant seem to get it to work. I saw some buggy coding in the examples I pasted aswell, but I think I've tweaked them all now and I still can't get results I'm looking for. To be honest, I'm thinking about taking the age validation out. I don't know if frameworks are for me lol


Thanks again though dude, your help was a big eye-opener.
