I am trying to urlencode this string before I submit.
queryString = \'eventName=\' + evt.fields[\"eventName\"] + \'&\' + \'eventDescription=\' + evt.fie
Note that the urllib.urlencode does not always do the trick. The problem is that some services care about the order of arguments, which gets lost when you create the dictionary. For such cases, urllib.quote_plus is better, as Ricky suggested.
