    Hi alen129,

    s/\\n/<br>\n/g is a search-and-replace regular expression, a good place to start is perlretut and perlrequick.

    Interpolation ('\n' vs. "\n" vs. "\\n") is discussed in a few different places, for example a bit in Scalar value constructors and Quote and Quote like Operators.

    Also, as mentioned as one of the points in the Basic debugging checklist, it's probably a good habit to get into to use a module like Data::Dumper or Data::Dump to look at the content your variables:

    my $Detail = 'Sep 30 2016 8:32AM CHP\nSep 30 2016 8:32AM SANTA ANA\n';
use Data::Dumper;
$Data::Dumper::Useqq=1;
print Dumper $Detail;
# - or -
use Data::Dump 'dump';
print dump $Detail;

    Both will unambiguously show you the content of the string in Perl's syntax, for example "Sep 30 2016 8:32AM CHP\\nSep 30 2016 8:32AM SANTA ANA\\n".

    Hope this helps,
    -- Hauke D
