Yes, you are correct. The featureset.Attributes has three fields: Name, Policy, and Stop_id. I only want the Stop_id in the comma separated list variable. I intend to use that variable to send to a Webservice in a script. I can make the Webservice and script work by using the selectedItem of a list (I define the labelField=Stop_ID). I want to send multiple values, in fact all of the values each time the function is run. If there is another way to do this, I would love to know. For example, if there is a better way to get the text value of the one field (Stop_ID) that is contained in featureSet.attributes, that would be fantastic. I would rather not, if I don't have to, limit featureSet.Attributes to one field only in the function (the fields are defined in the config.xml), as that would affect its use as a dataProvider for a grid.
