Wrong amount in total price

Hello,
I have set up a travel agency website using event booking. So far it has been going well. Now I want to be able to sell addons to the trip, such as additional baggage and so on. I have put in custom fields in a dropdown and put in the values. It all looks good, but... it doesn't calculate the extras into the total price.. so the payment processor is receiving a wrong price.. just the original price of the trip and nothing else.

Can you help me with this ?

Hi

Could you please make a screenshot of the custom field setting so that I can check it and guide you to correct it ? I believe it is just something wrong with your settings.

Regards,

Tuan
