Update multi value field Email with ItDuzzit

Hello, we are using itduzzit to connect Podio with a webservice. Is there somebody who has experience with Itduzzit? we are dealing with an issue that we can't update the multi value field "Email". We don't understand how to enter the values that Podio can read and update the information (e.g. "test@test.com, home" or "test@test.com;home;;" etc.).

Thanks in advance
Julian
