Hi Wendy

I tried creating new report , I have 1 main report and 3 sub report on this
on main report when I enter some invoice# and accountnum  data shows up with no problem,
but same time if I enter different invoice# and accountnum , there is no data return  on same query, I have checked my query so many times, donot understand this issue, what's causing this problem, since all the data pulling from same tables, why its
not pulling for some invoices,
