Once Appointment Placed, an email confirmation is not sent

Hi There,

I am having trouble with my appointment plugin. I fixed an issue so now appointments appear in my calendar. However, it is not sending email confirmations to the client or to myself when an appointment is placed. I just did two different test appointments. Can you help me?

So in essence, once an appointment is placed, a confirmation email is not being sent to myself (should go to littleblackdresspaperie@gmail.com ) and also to the client.

Please advise. I have granted admin access.
