Hello,
You are wirting about Registration Marks, but it is reservation email. Reservation and registration marks can be different.
Also it looks like legend for these tags is not actual. I used default settings and there is {CUSTOMER} instead of {NAME} and it works for reservation (registration will probably still use {NAME}).
You can copy tags from this example:
Dear Customer,
your Reservation was successfully saved.
{OBJECTS}
Object: {OBJECT TITLE}
Reservation Date: {DATE}
Quantity: {QUANTITY}
Price: {PRICE}
Deposit: {DEPOSIT}
{SUPPLEMENTS}
{/OBJECTS}
Full Price: {FULLPRICE}
Full Deposit: {FULLDEPOSIT}
Customer: {CUSTOMER}
Address: {ADDRESS}
Company: {COMPANY}
E-mail: {EMAIL}
Telephone: {TELEPHONE}
Fax: {FAX}
Best regards.
