Insert, update and Search CF script

This is what I am trying to do. It has to be DONE in Cold Fusion. I have a 'linked' Table called SchoolID_SubjectID that looks like the following: SchoolID SubjectID 2 3 2 7 2 56 3 7 3 24 4 1 etc, etc This is a LINKED table and is linked to two other tables, one callled schools (which has the field SchoolID) and the other called Subjects with fields Subjects and SubjectID What i am trying to do is create a FORM to insert and update (seperate forms) the School and Subjects values in the LINKED table. Once this is done, I also need a form created to SEARCH by product I am designing the site but need the Cold Fusion pages done externally. I can if you like call you and explain what I need to get done.
