I am having a hard time figuring out how to get this sript to work right. It is an AJAX function that is supposed to populate a dropdown box called Insect Family based on the selection made from the dropdown box for Insect Order. Then I want to submit the Insect Ffamily information and retrieve the record from the database. Problem is, I don't have my form right and don't know how the information is being passed along. I assumed that I would have the $_GET['familyID'] filled with the family ID for the selection when the submit button was pressed, but it doesn't seem to be working right. Here is the code:
Let me know what I am doing wrong. I currently get Notice: Undefined index: familyID in C:\Program Files\Apache Group\Apache2\htdocs\fizzyfish\functions\order_to_family.php on line 2. Then after that everything seems to work ok. The dropdowns are correct. I just can't seem to figure out how to actually retrieve the information from them.
Thanks in advance!

$familyID = $_GET['familyID'];
echo $familyID;
