I am using the sample called "Identify or find features near a location" I can get it to work with my data and show the fields I want but I want it to do something slightly different and I have not figured out how. The sample teaches you you can tweak the identifyTolerance to find features within a certain distance of a mouse click. I want to be able to do this with a specified distance in map units. For example instead of 110 pixels I want to be able to specify 100 meters.
