Amy,
Why do you have your results in an Accordion when you are only giving it one canvas?
Amy,
See if this works. I can not test as your map service is not accessible.
Don't forget to click the top arrow (promote) and to click the Mark as answer check as shown below:
Amy,
As I mentioned I can not test/debug your code because I don't have access to the map service you are using. You need to check your identifyParams and the URL, identifyParams.tolerance = 1 seems pretty low. Do you get to the Alert in the identifyFeatures function?
