Dependend drop-down in PDF form

Question

I thought this would be easy, but the tutorial I'm following is way more complicated than what I'm building, so I'm getting lost.
I'm making a form that has two dropdown lists, and the items in the second one need to depend on what was selected in the first one.
My first dropdown has three selections, and I've written a list of dependent selections formatted like this:
var TopicLink = {
    Planning:[
        ["-","None"],
                ["Border planning"],["border_planning"],
                ["Census issues"],["census_issues"],
                ["Citizens Guide"],["citizens_guide"],
                ["Congestion Management Process"],["congestion_management_process"],
                ["Csstp"],["csstp"],
                ["Delta Region"],["delta_region"],
                ["Economic Development"],["economic_development"],
For each of the three items.
I've pasted this into Other Tasks, Javascripts, Document Javascripts (Acrobat X), but when I right click on my second drop-down and pick the Actions Tab (On Focus, Run a Javascript), my JS doesn't appear on the list.
This is my first time touching a PDF form other than to fill one out.  What am I doing wrong?

Thanks George,
While working on this, I stumbled across a copy of LiveCycle ES2 that I didn't know I had installed in this machine.  For some reason I was able to figure things out much more easily in this program, so I managed to get it working without much issue.
Thanks for the reply!
