I've a small bit of javascript on my site that has a from with 2 selection
boxes, when you choose an option in the first box, the second one
re-populates its list accordingly.

But the second selection box can have varying amounts of entries, and this
means theres a lot of white spaces in the second selection box sometimes. Is
there any way to eliminate this? Here's my code:

<script language="JavaScript1.2">
<!--
var logos = new Array();
logos[0] = "Abstract";
logos[1] = "Adult";
logos[2] = "Animals";
logos[3] = "Company Logos";

logos[6] = "Danger";
logos[7] = "Eyes";
logos[8] = "Food Drink";
logos[9] = "Football";
logos[10] = "Horror";
logos[11] = "Kids";
logos[12] = "Love";
