Assistance Needed for Merging Emails in Table Column

Hi, I am having trouble with one of my tables. Specifically, the "Merged Emails (2)" column. I want this column to merge together the valid emails from the merged "Work Email (SMB)" column and the "Validate Email" column which is right after my "Email from ZI" column. Can you help me put in the right first and then statements in the "Merged Emails (2) column to reflect what I want? I can share my table link if that helps.
