PHP관련 질문이요...급해요...

APM을 통해 간단하 검색 페이지를 만들고 있습니다.

컴 사양은 젠투, Apach 2, PHP 5, Mysql 4 입니다.

search.php의 코드를 적어 놨구요, 웹의 검색 페이지에서 search를 하게 되면 그냥 원래 페이지로 돌아오게 됩니다. 검색이 안되는 것이지요.. 이것 말고, 그냥 디비 전부를 보여주는 페이지(allentries.php)는 제대로 작동 합니다 id, spot, cog, cog_definition 전부 출력됩니다만... more info로 링크된 페이지(view.php)는 먹통이네요.. 원래대로 라면, $id로 검색이 되어야 하는데.. 물론 디비와 연동 되는 것은 확인 했구요.. view.php에서 $id를 못 읽어 드리는 건 가요?? search.php에서는 $searchstring, $searchtype을 못 읽는 거구요??
에휴.. 초보는 힘들답니다...ㅜㅜ
어디를 어떡게 고쳐야 하나요...

아래는 allentries.php 하면 나오는 페이지 결과 일부 입니다..
