          from estitem e , itemlist i
          where   i.item = e.eiitem
          and l.lcontid='070038'
          group by e.eiitem, e.iplineno,i.idescrl, i.iunits) t
where c.call = b.call
and c.letting = b.letting
and c.vendor = b.vendor
and b.vendor = v.vendor
and b.call = l.call
and b.letting = l.letting
and l.letting = t.letting
and l.lcontid = p.contid
and p.contid = x.contid
and x.pcn= pr.pcn
and pr.pcn=g.pcn
and e.cn = g.cn
and e.pcn = g.pcn

Thanks for the reply.....My problem is the tow filed that I grab for the embeded query the values donot change with the resutl of the selected filed.
select c.iplineno, c.bidprice, b.vendor, v.vnamel,l.lcontid, t.datelet, func_get_county_name (ccnty1) county, e.iplineno, t.iunits,t.idescrl, t.eiitem
from bidtabs c, bidders b, vendor v, letprop l, bidlet t, proposal p, propproj x, project pr,estcatg g, estitem e,

          from estitem e , itemlist i
          where   i.item = e.eiitem
          group by e.eiitem, e.iplineno,i.idescrl, i.iunits) t
where c.call = b.call
and c.letting = b.letting
and c.vendor = b.vendor
and b.vendor = v.vendor
and b.call = l.call
and b.letting = l.letting
and l.letting = t.letting
and l.lcontid = p.contid
and p.contid = x.contid
and x.pcn= pr.pcn
and pr.pcn=g.pcn
and e.cn = g.cn
and e.pcn = g.pcn
