Hi, i've tried both your suggestions but can't seem to make it work. It gives me 2 errors:

X:\bla\script.pl Denemarken.csv xx.csv
syntax error at X:\bla\script.pl line 55, near "$elements["
syntax error at X:\bla\script.pl line 82, near "}"
Execution of X:\bla\script.pl aborted due to compilation errors.

This is my entire code:

if ($#ARGV != 1) {print "usage: input-file output-file \n";exit;} 

$inputfile=$ARGV[0];
$outputfile=$ARGV[1];

open(INFILE,$inputfile) || die "Bestand niet gevonden :$!\n";
open(OUTFILE,">$outputfile") || die "Bestand niet gevonden :$!\n";

$i = 0;

@infile=<INFILE>;

foreach ( @infile )
        {
      $infile[$i] =~ s/"//g;                
      
      @elements = split(/;/,$infile[$i]);

    if (!($elements[20] =~ /^\+45\s{1}\d{4}\s{1}\d{4}$/))

        }
