I am running into an issue with this plugin. I am trying to pass several mailing list names from Gravity Forms to Constant contact. Constant contact requires them to be submitted like this:
If you are using multiple lists it should look like this &Lists=List1&Lists=List2&Lists=List3
This plugin is passing the list selection along like this: &Lists=List1,List2,List3 Is there a way to force the plugin to use the entire field name each time?
