I wonder that the View at gone to EOF and some data are lost!
How can I print the report with some special field!

e.g. Orders has a field Develop_cost (development cost is optional!)

if this field is great than zero, need print the development cost line!

but when print the report summary, the field setting condition is gone!

I set the condition is: !empty(develop_cost)
or set: develop_cost > 0
or set: type("develop_cost") = "N"
...
but do NOT print what I want!
