Message: [QUOTE="Kevin Shay, post: 4746987"] The problem may lie in the first line of code above: @recipients = CGI::param('csvdata'); It sounds like you have a single HTML form field called csvdata, into which the user enters multiple lines of text. If that's the case, the CGI module will not automatically turn this into a list. It's a single value. So the entire set of data is being placed into the first element of @recipients. When you print that one-element array to a file, it simply prints that one element; the element happens to have multiple lines, so the resulting file will have multiple lines. Then, when you re-open the file and do this: @recipients = <ADDRESSES>; Perl reads the lines of the file into the array, one line per element, which is what you wanted in the first place. So you could probably just do this to avoid the whole temp file workaround: @recipients = split(/\n/, CGI::param('csvdata')); As for the actual chomp problem, it may have something to do with the way different operating systems encode newlines differently (\n on Unix, \r\n on DOS/Windows, \r on Mac). Depending on which platform the user's browser is running on, you may not be getting just \n characters separating the lines. So you might want to normalize everything to \n newlines: my $csvdata = CGI::param('csvdata'); $csvdata =~ s/\r\n?/\n/g; @recipients = split(/\n/, $csvdata); Kevin [/QUOTE]
