Hello,
I am having a really hard time getting a combobox to populate in an existing web app I am working on so I decided to re-write an old ComboBox sample and still cannot get it to work. I really want to get it to work using the new coding structure. Here is the link to the old sample:

Here is my attempt. Thanks in advance for any help !

<title>Populate dropdown list with unique values</title>
