Unfortunatelly, Report Builder don?t like to have null in the fields he works. So, RB put '' (empty string) in the field that have the NULL value. I cracked my brain to find this and, to make my work easyer, I registered a RAP function VarIsNull that tests if the field is '' and returns true. Hope this can help.
I had to do it ?cause I?m working outside delphi, with the reports stored in a database . So, I can?t use DataPipeline or any of that stuff, only the rap functions. If you know a different way to do it, please tell me.

try the following:
if Datapipline.FieldObjects['FieldName'].IsNull ... (do something)
