Opening a window Can't Post

I'm trying to spawn a new browser window, but don't know the perl command. I'm checking a form for required fields, and if the necessary info isn't there, I want a new window to open where I can instruct the user which fields they missed and leave the filled in form in the main window. How do I spawn a new window and direct print statements to it?

it would probably be part javascript, the part to open a new window, it would be easy from there, just pass the URL something like,password,whatever

then your code might look something like this

$missedfeilds = param('missedfeilds');
@feildsmissed = split(/,/,$missedfeilds);

print "Sorry but you did not fill out all the feilds", join("< br>",@feildsmissed), "< br>Please try agian";

that is just an example, I dont know if it'd work. It's kinda late and Im losing sleep :)

Perl cannot control what the browser does. If you want your script to open in a new window just do this:
<form ... target=_blank>
Note that no matter the outcome, the script opens in a new window.

  I use perl to check if the parameters are defined,
if not then print message else display page....

if (!$VAR1 || !$VAR2) {
html_init(); #PAGE HEADER
print "
<h4>SORRY! </h4>";
print "<h5>VAR 1or VAR2 was not entered.</h5>
<b>Please use the back button on your browser to return to the form.</br>";
empty_fields(); #PAGE FOOTER
else { .... display next page...}
