Php Forms Wont Submit In Linux(centos)

hello,

I need help here...
My index.php page wont submit even after clicking the submit button in a Linux(CentOS) environment....
It would sort of just refresh and then it goes back to the same page again..
Did I forget something to set in my php.ini??

Im sure that my codes are alright... As this system that im running is working fine in a windows environment..


i badly need your help here.. thanks
