Re: how do I find one number that matches in elements of same array and combine those elements?

Nodes are written in html. Please use <br> tags to put some line breaks in so it's easier to read.

As to your problem (which I'm not completely sure I understand, but I think I have some idea what you're asking), if you want to combine multiple lists, remove duplicates, and sort the result, you're looking for a hash. If you make a hash key from each list element, the duplicates will automagically resolve themselves, and then you can

sort keys %whatever_you_name_your_hash

to get the sorted result back as a list. Edit: fixed and noted.

For the love of all that is good and holy, DO NOT tell people to wrap their entire post in code tags. Ever. Update: Instead point them at Writeup Formatting Tips, Markup in the Monastery and Perl Monks Approved HTML tags.	[reply]
