I'm sure I must be missing something simple, but I can't seem to figure out what it is. I have a dropdown box. The page is supposed to pull information from a database based on what is selected. I do this with the procedure posted below. It does it right when you first navigate to it, but changing the value in the dropdown box won't work. It gives me an error saying "Error: Object required cboId". The thing I don't get is that the error happens inside the script. How can it not recogozie cboId when the script is only executed when cboId is changed?
