Hey there,
recently, somebody asked me if it is possible to create an invoice with the page design plugin AND to print the total sum of all positions on the invoice. Here is what it should look like. This is a tutorial how to get the 210 € on the invoice.

Of course this example is very limited. Usually, the products should be stored in another table etc… But I hope you get the idea.
