Variables not changing problem...

I'm using the function below to create a listing of name/value pairs to use in Flash. The first time it runs it works fine, but then after the first time, it uses the originally used variables. So if the URL looks like this: mydomain.com/hum_images.php?hub_section=product&hub_subsection1=FOOTWEAR The first time it will output correctly and the debugging lines will properly output: FOOTWEAR product However, if I then enter: mydomain.com/hum_images.php?hub_section=product&hub_subsection1=APPAREL function selectHubImages ($hub_section, $hub_subsection1) { global $db; $result = mysql_db_query ($db, "SELECT navigations.nav_label, navigations.nav_parent, navigations.nav_name, navigations.nav_menu, product_items.product_section, product_items.product_parent, product_items.product_name, RAND() AS 'random' FROM product_items, navigations WHERE navigations.nav_name = product_items.product_name AND product_items.product_section = '$hub_section' AND product_items.product_parent = '$hub_subsection1' ORDER by random"); $n = 1; echo "$hub_subsection1<br>"; // for debugging echo "$hub_section<br>"; // for debugging while ($row = mysql_fetch_object ($result) and $n <= 5) { echo "thumb" . $n . "=" . $row->product_name . "&"; echo "thumb_subsection_two" . $n . "=" . $row->nav_parent . "&"; echo "thumb_label" . $n . "=" . $row->nav_label . "&"; $n = $n + 1; } echo "thumb_vartot=" . ($n - 1); echo "&done=1&backspace="; mysql_free_result ($result); }
