hi hilmar! it's me again.
i just want to get some ideas from you. this is also part of my question earlier, about the sorting of data, and i forgot to tell you that, the reason why i put my data at the header band of my report and why i used an array was that im going to make a computation with products that is under to the same category as well as im going to create some labels.

for example:
joe rent 3 different video tapes; 4 action movies(2 foreign and 2 local movie), 2 suspense movie (1 each forign and local movie) , 3 comedy movie(local movie). now, all the action tapes are 5% off, and suspense tapes are 10% off, and the comedy movies are 2% off.

my movie id's:
action movie -> movie101
local -> movie101-1
foreign -> movie101-2
suspense movie -> movie102
local-> movie102-1
foreign -> movie102-2
comedy movie -> movie103
local -> movie103-1
foreign -> movie103-2

so im going to sort my tapes (movie101-movie103), and then im going to create a label top of each category(ACTIONS,SUSPENSE,COMEDY...) as well as compute each category rentals.

hope you understand what i mean by this problem. thank you so much hilmar!!!
god bless!!!
