I have a table composed of four field
field 1 Student Name
Field 2 Mathematic, Chemistry ,Biology
Field 3 Physic Mathematics Economic
Field 4 Biology chemistry Mathematic

how can I print in one report the same subject only.
example "only the mathematics students appear"
or if I want to print only student with chemistry subject"
it seems I am turning in a deep loop

I guess it's complicated

Any help
