Trying to get InfoWindow sample to work

Hello all - I hope someone can take a moment to help me out. All I want to do is click on my points and show an InfoWindow. I used this example http://help.arcgis.com/en/webapi/javascript/arcgis/demos/query/query_showinfowindow.html

I replaced the layers with my own and can see my points on top of the background layer. I also altered the fields in the query. When I click on the points, nothing happens. Here is my code:

I'm obviously new to this but I can't figure out how only swapping out the data layers in the sample results in it not working. Does it have something to do with different geometry types? I commented out the code about the symbol since I have points, not polygons.

Thanks!
