Summary page


I have one problem and need some help to resolve it!

I need to create 6 steps form with text fields, checkbox, radio buttons and one texarea. Some of radio and check buttons contains numbers -> prices!
All filled fields as shown on the summary page. It’s all correct and works nice.

My problem is:
At first on the last page (summary) I need to add total sum of colected prices and one check box (“I agree”)!?
Second question -> Can all colected data including summary of prices be sended, like attachment (pdf it’s possible) and into email to recepients?

I’m also willing to pay for it!

Best regards,

p.s. I’m using Typo3 9.5 and EXT:form
