不管是那一句都报错，是什么地方写错了吗？

sql="select tbtk.tmid,tbtk.title,tbkc.kcm,tbtk.category,tbtk.chapter,tbtk.kao,tbtk.level from tbtk,tbkc  where tbtk.kcid=tbkc.kcid  and  tbkc.kcid = "& subjectview &" and category="&typeadd &" order by tbtk.chapter,category,tbtk.tmid desc"
这样时正确
tbtk=request.cookies("username")是我后来添上的，就不对了。是不是语法有错误？
