Is full Payment available?

Hi,

I need people to pay the full amount, not only a deposit. Is there a way to do this?

Also, I need to have 3+ categories of users that will pay different prices (Students / Kids / Adults ). Is there a way to calculate the total amount based on these categories?

In the page I linked, you can see that I added 3 fields, with the possibility to chose what kind of category the user is and how many people are going to book.

What I need is the system to add up these fields and let the user pay the correct total amount in full.

Thank you for the help
