Send E-mail smart service not sending to the second email recipient

In the documentation for the Send E-mail smart service, it says to put a semicolon between email recipients.

This is the expression I am using.

= toemailaddress(
  pv!spkrRecord['recordType!PMSO Speaker.fields.speakerEmail']
);
toemailaddress(
  pv!parishProfileRecord['recordType!PMSO Parish Profile.fields.parishContactEmail']
)
 

However, the first recipient receives the email, but the second one does not.  What am I doing wrong here?
