Hi,
I am (still) looking for a possibility to make a sum that is made from different datasets.
The input consists of: ‘name’ - ‘type’ - ‘number’.
There is a dataset that has a price for ‘species’ per species.
Each person has their own account page, here I want to get the result of this person that is filled in at the input. By looking at the price of ‘type’ multiplied by ‘number’, the result should be a total.
To maybe make it easier I would like to share the page with you 
Erwin, you won’t get an answer if you put it like this. It’s too abstract. Show us a screenshot of what you want, show us the code you got so far, and maybe we can help you better. But " a sum that is made from different datasets" is incomprehensible.
Hi Giri,
It took a while but now I’m going to tackle this website again 
I have tried to describe as clearly as possible what I want to achieve with the website.
The intention is to keep track of consumptions and a page per person containing an overview of his consumed consumption, his payments and what is still open in terms of payments.
I use 3 datasets
1, Assortment (#1)
2, Payments
3, Name (#2)
1: name (naam) (#2)
2: consumption (consumptie) (#1)
3: count (aantal)
4: Total (price) of all consumption of this person
5: Total of all paid consumptions of this person
6: Is total of price consumpions minus paid consumptions
The price for a consuption do i have in a “Assortiment” dataset.
I hope this clears things up a bit and that there is a solution I can use
