For anyone having this issue, the solution posted here works:
https://community.quickbase.com/quickbase/topics/sending-email-notification-using-an-email-formula-f...Basically, it seems that even though Open Notifications allows you to pick the "email list" field, the email notification system that quickbase has doesn't respect the semicolon delimited list that the field generates.
I think this is a bug/oversight within the notification system, but the workaround is to create individual email formula fields and list them within the "specific list of email addresses" field on Open notification page.
