option_array[0] = new Array("Select an Area"); // This is the first (blank) category. Don't mess with it.

option_array[1] = new Array("Select an Area",

var text_array = new Array(num_of_cats);

text_array[0] = new Array("Here's how you use this box: First, you select a category in the Category drop-down. Then, select a link from the Link drop-down. Then, read the description in this box, or click Go to go to the page. If you ever need to see this help again, just go back to the top option in the Category box."); // These are general instructions. Change them if you want, or keep them if you don't.

text_array[1] = new Array("Karachi Area Selected.", // Note that the first entry here is a general description of this category. After than, they're descriptions of each link. Make sure that you don't put the first link first; the general description must be first.

url_array[1] = new Array("#", // The second category; the first "real" category. Note the initial #. That is the category which says "Please select a link." It doesn't need a URL. Start putting the other URL's in after that first line.
