Hi, I'm a Perl noob so I don't know if it's a very stupid question. I have been assigned to write a program to do some stuff with excel files. I need to read the first column of IDs and ensure that all the corresponding etries in subsequent columns for each ID is a unique comination of characteristics. E.g. If I have 3 columns, "ID", "Product", "price", I need to check if all the IDs have a unique product and price. I can figure out a tedious C-ish solution for this but I believe Perl must have a prettier solution. I was trying out the module  Spreadsheet::Data which returns an arrayref of arrayrefs. Problem is I can't seem to be able to dereference the array without accessing each element separately. I mean, I know how to do  $$data[10][20];, but I can't use the array as a whole in loops or if statements. Can anyone please explain how to go about doing that, or even better, if you know of a better way to solve the problem, please let me know. It'd be a Huge help. Thanks, -m
