When my submissions are emailed it only comes through as UNDEFINED

My account name is SLT2 for sugar land taxi form

Hi,

When I checked your forms' email notifications it appears as though the body of the notification has been deleted:

Which is why the only thing you receive in the email is the "undefined" message.  You can always revert your form back to a previous revision if this was done in error:
