311720 PHP email form script

HI I need a php email form that based on what item they pick from a drop down box it will send an email to a certain address. Each item in the dropdown box has a different email address tied to it. Each email address is tied to a autoresponder so the email address of the person who filled out the form will have to be seen by the autoresponder so it can response to that person All the contact information must go into a database. It could be just a flat file (Excel format if possible) After they complete the form that must go to a thank you page It should be simple so I can just copy the code and put it on different html pages I also need to add or remove items from the dropdownbox, do not need an admin section just need to be able to put a * in front so it does not show in the form. Also all fields need to be filled, the form can not be submitted iif all fields are not completed. Example Name Address Email Address Comment field Dropdown boxes Email addresss tied to North East north at [login to view URL] South east South at [login to view URL] west end West at [login to view URL] Etc
