I am setting up a fedora web server and have an html form that when clicked will call test.cgi. Test.cgi will then write to a crontab. My problem is that my cgi script(var/www/cgi-bin/test.cgi) does not write to my crontab file(home/jma/Documents/cron-tab) at all. Permissions for my test.cgi file is 755. Permissions for my cron-tab file is 777(I know I should change this but just trying it for now so I can write to it).
Code for test.cgi 
#!/usr/bin/perl
use CGI;
print "Content-type: text/html\n\n";
open(OUT, ">>/home/jma/Documents/cron-job");
print OUT "blah\n";

Can anyone tell me what I am doing wrong and why test.cgi does not write to cron-tab correctly?? I guess this is probably not the safest way to process the data. I've been hearing that I shouldn't write directly to a crontab file. Can anyone tell me an easier way to do this? Thanks!
