yes, as joe said, please post the errors .. if you are not getting errors for some reason, try troubleshooting the sql query itself. below, i make a string called $sql and echo it to the screen.
an easy way to test to see if this is a good sql query or not is paste the output into phpmyadmin and see if it reports any errors.
PHP Code:
$sql = "INSERT INTO quote (sender_firstandlast, sender_companyname, sender_email, sender_phonenumber, how_recieve, websitetitle, what, websitedetails, websitebudget, how_pages, completiondate, currenturl, chooseany, size, scripts, databases, scriptdetails) VALUES ('$sender_firstandlast','$sender_companyname','$se
nder_email','$sender_phonenumber','$how_recieve','
$websitetitle','$what','$websitedetails','$website
budget','$how_pages','$completiondate','$currentur
l','$chooseany','$size','$scripts','$databases','$
scriptdetails')";
echo $sql;
