Is there a reason you aren't simply storing plain JavaScript in cpy.js? Also do you have `<p>` tags in your cpy.js file? You may also want to look at the `header()` method from the CGI docs. Update: You should benefit from reading the links in this post. Martin	[reply] [d/l] [select]

Honestly, I'd just suggest you start by reading a tutorial on CGI, or something like that. That is not a CGI script, that's plain HTML. That is not a .js (Javascript) file, that's Perl, except with <p> tags before each line. It appears to be meant to generate your javascript, but then I'd ask why. It's static anyway, right? Then there's no need for it.	[reply]

the dynamic calender is not working..... What error are you getting in the web server log or in the browser's error console?	[reply]

I have a hard time believing you found that message in either the web server log or in the browser's error console. Perhaps you misread my question?	[reply]

`print "Content-type:text/html\n\n";` [download] Javascript is not text/html. Usually JS is application/javascript or text/javascript. `cpy.js` .js is an unusual extension for a CGI program. I doubt that your web server is executing cpy.js unless you have tweaked your configuration. I would recommend using an appropriate extension like .cgi. Try loading the Javascript directly. http://localhost/cpy.js or whatever. If you get Javascript then you're on your way but I expect you will get a mangled version of the perl script since it's being served as html rather than javascript. As ikegami recommends, check the server log and the error console. If you have Firefox around, I'd recommend using a developer addon like Firebug to see what is going on inside the constructed page.

Apart from the other problems, keep in mind that `<<eof` is equivalent to `<<"eof"` which means that the text enclosed by the heredoc will be handled like a doublequoted string. That is $variables are interpolated, \x escapes are processed etc. etc. ... Maybe the browser doesn't get the text you think it does. Jenda Enoch was right! Enjoy the last years of Rome.
