Send Email Attachments

I have a process that creates 3 documents.  I want to attach all three documents to the Send Email service but it is only recognising the first in the list.  I entered them initially in the following format:

pv!attach1; pv!attach2; pv!attach3

I then created a separate pv and appended all 3 attachments to it and then added this to the attachments.  This too only included the first document in the list even though it displays in the process variables as:

"attach1"; "attach2"; "attach3"

Does anyone have any suggestions as to how I can make this work.

Alternately, does someone know how I can get the document id by the document name?

Any suggestions would be appreciated.

Thanks
