Open the basic settings for the resource.
Specify the total share count.
This is the total number of adults and children's price options.
Now create two shared price options. Children and Adult.
In the children's rate, specify the price cheaper than in an adult.
If 20 adults and 20 children's tickets are available for booking, then in both tprice options in the Share count field, set 20.
The result is such a configuration.
You can also divide the total number of price options between adults and children.
For example, allow for booking 5 children and 15 adult price options.
To do this, specify Share count in the children's price option - 5.
In the adult price option - 15.
In this case, the configuration looks like this.
