Well, there's a few things I noticed that are missing from your example, which may or may not be present in your actual code. And I hate to assume :-)

Are there end tags for your SELECT and FORM tags after your while loop that you have in there?

As for things that may certainly be breaking it -- the OPTION tags within your SELECT statement do not require end tags.. and I'm not sure, but end tags may actually break them. Unless thats part of the new XHTML thing...

Additionally, you may find that not printing out HTML code by hand is a good thing. While perhaps a few small lines may be acceptable, you appear to be using enough HTML to warrant using CGI, which can assist you with any of those HTML coding issues anyway. However, I sometimes find that certain projects are better off using an HTML Templating scheme such as HTML::Template and Template::Toolkit.

Lastly, you may want to consider trying fetchrow_arrayref(), which won't yank all the results into a single array. You can then use it like this:

while (my $row = $sth->fetchrow_arrayref()) { ## Make our HTML look better if no data. $oid = "&nbsp;" if($oid eq ""); $date = "&nbsp;" if($date eq ""); $username = "&nbsp;" if($username eq ""); print <<HTML; <OPTION>$row->[0] $row->[1] $row->[2] HTML }
This example, of course, isn't incorporating CGI, which would again probably be a good idea. And you did define earlier in your code, using "my", your $oid, $date, and $username variables, right? :-)

But if none of that does the trick, perhaps you could be more specific about how things aren't working for you, and what it is that is happening. Good luck!
