Originally posted by: ryehI spoke with Heather as I was on-site today. So I, too, had initially misunderstood the question. The problem is, Heather wants to send the e-mail to AddressA and cc: AddressB. Based on the data conditions, sometimes AddressB is null/blank. In that case, the e-mail node errors. The work-around we came up with was to merge both addresses and use only the To: field. If AddressB is null/blank, then AddressA is used, otherwise the two are concatenated with a semi-colon ( ; ) separator.
