That is not my code. I wouldn't use recno() in an SQL. Probably you are thinking your or someone else's code is mine. What I suggested was:

SELECT COUNT(*) FROM subjects where sno = this.Value  into ARRAY cct

With that one it would be:

sno = subjects.sno
code = subjects.code

SELECT COUNT(*) FROM subjects where sno = m.sno and code = m.code into ARRAY cct
