i have a table in access containing data like:

PaperID--School--PaperID---PaperTitle--Noofstudents---Duration---ListofModules
paper 1---SEG----EG1832---Mechanics---- 286----1.5(hrs)---EG1832
paper 2---SEG----EG1833---ElectricalPrinc--375--1.5 -------EG1833 EG1952 EG1903
another table with:

module students
EG1832 ----- 111411H
-blank ----- 111380Y
-blank ---- 151621H
EG1952 ----- 198653H
-blank ----- 545411Q
- blank ---- 111411H
if let say student;111411h is taking EG1832 and EG1952, then output:

Conflict modules No.ofstudents student(adminNo)
paper1 : paper2 1 111411H
anyone tell me how to go about doing this?

thanks in advance!

The tables seem incomplete. How do you know that EG1832 and EG1952 conflict? Are there dates for the papers somewhere?
Once you had a pair of conflicting modules, you'd need to create two temporary tables of students taking each of the two modules, then select students that appear in both tables.
