Re^2: find unique elments and sum the corresponding values

Hi..many thanks for the reply, I couldn't understand the main part of the script, the while loop. However, when I exscuted the script I got this message: Global symbol "$sum_of" requires explicit package name at SortSum.Pl line 22. Execution of SortSum.Pl aborted due to compilation errors How can this be fixed? and if possible can you explain the script to me so I can learn? thanks

You really need to spend some time reading documentation. If you haven't a copy of 'Learning Perl' you should at least read through the Getting Started with Perl section in Tutorials. True laziness is hard work	[reply]

Don't know if you already saw my updated code. I added some comments and fixed that syntax error. Had a bad typo in the "print result" section.	[reply]
