My English is poor, excuse me. We make excursions to different cities and a few hours. So we created the corresponding blocks in an excursion on a date and a specific time. We practice adult price, child and child under 5 years. We bought the Add-ons module to offer the language of the guide and ask the names and ages of each participant. The problem is that we can not have summary list for a block (tourist trips) with the total adult, the total child, the total child 5 years old, the total in each language and list of participants. We have created a module to print a summary list.
