Hello monks!

I am trying to connect to my database while the user is filling out the form. It works as such: the user fills out a text box, without submitting the form, I would like to have a pop up window from where the user can have more options that are coming from a database.
Here is my code:
IN HTML I HAVE:

<input type="text" name="textBox" size="8"> 
<a href="javascript:priceList('form.textBox.value');">Price List</a>
[download]

IN JAVASCRIPT I HAVE:

function priceList(text){
win=window.open("cgibin/getPrice.pl?textBox="+text,"","width=250,heigh
+t=240")
win.creator=self
}
[download]

IN PERL I HAVE:

use CGI;
$q = new CGI;

$partNumber = $q->param('textBox');
print ($partNumber);
[download]

Thus, as you can see in Perl I am printin the result of what i have got. The result on page that I get is UNDEFINED.
What am I doing wrong?
Thanks Monks I am out of guesses!

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
