Query outputting all rows, I just want one.

Question

On a form, when submited contains a few variables in hidden form controls.
There is a loop in the form that outputs <li> items from a database, and a button with each list item, you click the button, it deletes that item.
But...it looks like the form is passing the IDs for all the <li> items. I just want to pass the id of one item. I am getting an error "Invalid data (then a list of all the IDs) for CFSQLTYPE CF_SQL_DECIMAL.
The button in row 5 and the <li> in the loop starting on line 3 are the question.
<form action="update-sort.cfm?faculty_id=<cfoutput>#qGetFacultyCV.faculty_id#</cfoutput>" name="sort_serialized"method="post" id="frm-sort">
  <ul name="anitem" id="sortable">
    <cfloop query="qGetFacultyCV">
        <button OnClick="document.forms.action = 'delaction.cfm'">X</button>
        <cfoutput><li id="section_id_#qGetFacultyCV.id#" class="ui-state-default">#qGetFacultyCV.full_citation#</li>
         <input type="hidden"  name="id" value="#id#"/>
      </cfoutput>
    </cfloop>
  </ul>
  <input type="submit" id="deleteBtn"name="delete" value="Delete Publication"/>
<input type="submit" value="ADDPUB.nextval" style="display:none">
  <input type="submit" id="saveBtn" value="Save" style="display:none" OnClick="document.forms['sort_serialized'].action = 'addaction.cfm'" >
  <input type="submit" id="editBtn" value="Save"style="display:none" OnClick="document.forms['sort_serialized'].action = 'updateaction.cfm'">
  <input type="submit" id="sortBtn" value="Save"style="display:none" OnClick="document.forms['sort_serialized'].action = 'update-sort.cfm?faculty_id=<cfoutput>#qGetFacultyCV.faculty_id#</cfoutput>'" >
  <input type="hidden" name="faculty_id" id="faculty_id" value="<cfoutput>#qGetFacultyCV.faculty_id#</cfoutput>" />
</form>
The action page is simply
<cfquery name="addpubnumber" datasource="db_cie">
INSERT INTO PUBLICATIONS (id, full_citation, faculty_id)
VALUES (ADDPUB.nextval, '#full_citation#', '#faculty_id#')
</cfquery>

Answer 1

What you observe is in fact the expected behaviour. By default, when a form is posted, all input form-fields of type 'hidden' are submitted.
My suggestions are as follows:
1) Use cfselect. It fits the situation you describe much better. 
2) Give each submit field a name.
3) Avoid the duplication in posting qGetFacultyCV.faculty_id as a URL variable in the form's action and as a hidden form field. I would post it as just a hidden field. This has the advantage of being more secure.
4) It appears that addPub is a struct. If so, then replace ADDPUB.nextval with #ADDPUB.nextval# as the value of the form field.
5) Use cfqueryparam.
When you put it all together, the result will be somelike
<form name="sort_serialized" method="post" id="frm-sort">
  <cfselect name="citation" query="qGetFacultyCV" display="full_citation" value="full_citation" />
  <input type="text" name="added_id"  value="#ADDPUB.nextval#" style="display:none">
  <input type="submit" name="delete"  id="deleteBtn" value="Delete Publication" OnClick="document.forms['sort_serialized'].action = 'delaction.cfm'">
  <input type="submit" name="saveBtn" id="saveBtn" value="Save" style="display:none" OnClick="document.forms['sort_serialized'].action = 'addaction.cfm'" >
  <input type="submit" name="editBtn" id="editBtn" value="Save" style="display:none" OnClick="document.forms['sort_serialized'].action = 'updateaction.cfm'">
  <input type="submit" name="sortBtn" id="sortBtn" value="Save" style="display:none" OnClick="document.forms['sort_serialized'].action = 'update-sort.cfm'" >
  <input type="hidden" name="faculty_id" id="faculty_id" value="#qGetFacultyCV.faculty_id#" />
</form>
and on the action page
<cfquery name="addpubnumber" datasource="db_cie">
INSERT INTO PUBLICATIONS (id, full_citation, faculty_id)
VALUES (<cfqueryparam cfsqltype="cf_sql_integer" value="#form.added_id#">,
    <cfqueryparam cfsqltype="cf_sql_varchar" value="#form.citation#">,
    <cfqueryparam cfsqltype="cf_sql_varchar" value="#form.faculty_id#">)
</cfquery>
