Thanks! I think I am getting it.
To store the Fee in a session on the registration form I have the local delivery cities in a drop down which pulls from the city delivery table.
I can use the eCart Set session variable and in the fields:
Trigger: select the city name column from the table (recordset)
Session name: flowerfee
Value: select the fee column from the table (recordset)
Is that correct?
thanks!!
