How to display value in mail

Hi
I am using conditional logic to choose Online Course or Classroom Course. Selecting one of the options shows a drop down of the courses available. Selecting a course then displays the price.
This seems to be working fine.
The problem is showing the price in the mail.

The form code is:
<!– COURSES –>

<!– TYPE OF COURSE –>

<div style=”padding-top:20px;”><label>Type Of Course (required)[select* course-type first_as_label “– Choose your Type of Course –” “Online Course” “Classroom Based Course”]</label></div>

<!– TYPE OF COURSE END –>

<!– CHOICES IF ONLINE SELECTED –>

[group OnlineCourses]
<div style=”padding-top:20px;”><label>Online Courses (required)</label>
[select* online-course first_as_label “– Choose your Course –” “RYA Essential Navigation and Seamanship Online Course” “RYA Short Range Certificate VHF/DSC Radio Online Course” “RYA Day Skipper Theory Online Course” “RYA Coastal Skipper/Yachtmaster Theory Online Course” “RYA Professional Practices & Responsibilities Online Course” “RYA CEVNI (European Waterways) Online Course” “RYA Safe & Fun Safeguarding Online Course”]
</div>
[/group]

The email code is (note- I have left the Payment Amount empty of mail-tag as Nothing I use seems to give the correct result):
The following person has provided information in request for a Course/Charter Booking

Full Name: [full-name]

Email Address: [email]

Address: [house-number] [street]
[town]
[city]
[county]
[postcode]

Telephone: [telephone]

Course: [online-course][classroom-course]

Payment Amount: ￡

Date of Birth: [_format_date-of-birth “d M Y”]

Sailing Experience: [experience]

Where did you hear about us?: [refer-from]

Additional Information: [additional-info]

Since I am learning to use this plugin from scratch, I think the problem may be in my form code but unsure where

Any help/advice would be appreciated

Thanks
Malcolm
