do while not cmd.eof
bigclassid= cmd(bigclassid)
bigclassname = cmd(bigclassname)
%>
cmd.movenext
loop
end if
cmd.close
set cmd = nothing

set cxd = conn.execute(select * from smallclass where bigclassid= & tempid)
if not cxd.eof then
do while not cxd.eof
smallclassid= cxd(smallclassid)
smallclassname = cxd(smallclassname)%>

loop
cxd.close
set cxd = nothing
