Hello!

There is probably a function of product costing under the 'payment' for this I can not find any documentation. A test has also not helped me, because the values ​​will always be displayed with USD instead of Euro.

Actually I only need a simple line output. Entered the quantity * price = total price
I'm looking for for quite a time in tutorials but a query on the amount I find just do not only check boxes and drop-downs.

Here is the link to the form I'm working on: Reservation

In addition to or below the "Menge" of the total price of the item should be returned.
Actually, should not be a great work, but somehow I turn today in the district ....
The form is also not equal to PayPal it go is merely a reservation. The goods are later picked up and paid cash on the spot.

Can someone help me how and where the command must go?

Thank you so much!
