Combining Sub Form data with Main Form data

Combining Sub Form data with Main Form data

I am new to ZOHO creator and have a fairly simple requirement for collecting online Data. I collect the data from a form I have created which has a sub form to collect peoples names and details.
 
On completion of data entry I need it to email the details entered. My form does this fine but the data from the subform does not come across, all I get is the subform "record ID"  I think.  
 
Below is the date auto emailed.  the bit in red is from the subform and doesn't give the names or details submitted.
 
Can anyone help me how to fix this in my subform?
