Vývoj webových stránek -- 2

Potřebuji opravit webové stránky I had to write a sign up form website, it's actually only start Page (Index), multi page sign up form made with bootstrap and than you Page. I need to make this bootstrap sign up form work with MySQL database, using PHP, simply to get the information users insert and submit saved. I have it layed out, but it doesn't work. Need somebody to review and repair my mistakes. I am not profesional web programmer, so probably made some mistakes. I was using templates and tutorials. Probably some minor mistakes, but I am quite lost. Experienced programmer should make it work easy. Maybe add some features too, like automated sending to email after signing and overall smoothing the whole site.
