Quite many issues here, some big, some smaller. I'll try to comment on some without any particular order of importance.

1. On line 9 you try to concatenate some unknown constant. It should be either a variable (i.e. $error, but defined somewhere) or mysqli's error function mysqli_connect_error().
2. I strongly advise against using HTML tables for positioning elements. This is not strictly an error but it is a bad design practice. Google for semantic html. In your case a table within table calls for problems, since tr tags are already messed up
3. There is no need to disconnect from DB and then reconnect on line 15
4. The real problem is that the code for inserting into DB should trigger only on submitting the form probably on the for.php page.
5. The $_POST['option1'], $_POST['option2']... elements do not exist since they have not been defined anywhere in the form. You should probably use $_POST['radio1_1'] since this is the name of your radio button. Probably you should have more radio buttons for each question.
