Body
For the drilldown, you need two reports: one that has all the records for an instructor, and one that has all the details for a particular student with that instructor. If the columns you want to display are substantially the same between the two reports, then you can actually do this with a single .asp file, but I'll assume you want to have two files. First, make the detail report. This should get a student ID and instructor ID from the querystring. Presumably, there should also be an academic year or period or some such time limit. <pre class="lang-vbs prettyprint-override"><code><html><head><blah blah blah> <% dim AY, SID, IID, SQL '-etc. AY = Request.Querystring("AY") SID = Request.Querystring("S") IID = Request.Querystring("I") '- validate the inputs and assign default values as needed %></head><body> <% SQL = "SELECT StudentName, Course, DateofClass, Attendance FROM AttendanceView" SQL = SQL & " WHERE StudentID = " & SID & " AND InstructorID = " & IID SQL = SQL & " AND AY = " & AY '- or whatever other filters are needed '- open a recordset and write it out, probably in a table '- close recordset, close table %></body></html> </code></pre> Then, in the main report, when you're writing out the row for a student, make one of the columns a link to the detail report. <pre class="lang-vbs prettyprint-override"><code>'... response.write "<td><a href='DetailReport.asp?I=" & rs("InstructorID") response.write "&S=" & rs("StudentID") & "&AY=" & rs("AY") & "'" response.write " title='Click to see details' target='_blank'>" response.write rs("TotalAttendance") & "</a></td>" '--- </code></pre> I've put a target="_blank" on the link, but with a little bit of JavaScript, you can make the detail report come up in a popup window/overlay instead. Also, if you prefer, you can put the detail link in its own column, so instead of clicking, say, the total attendance number, the user would click a plus sign or the word "details" or an arrow or something. The basic idea is the still the same, though: put the identifying information for each row into the link, and then the detail report can read it from the querystring.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
