Hello swathip, thanks for your response!
But what do you mean under "conditional formatting" - to hide fields that I don't need? Anyway if I just hide rows I don't need it won't work for me, because I have Total fields and they would be calculating with the rows I don't need to be calculated :(
My first attempt (as you said) was to filter data while I getting it, but unfortunately I didn't understand how, maybe there is topic about how to do that?
Thanks in advance,
Leonid.
