Making totals with registers

Thanks @Sam.

Any idea how I can solve it with this code?
Here I made a fori loop (as I asked earlier today). In every loop, I want the total of only this loop, but I also want to make an overall total that needs to be put in the first row of the table…

{{ header }}
|Kinderopvang||| {{ $0 | currency }}

{{ header }}
{% stripnewlines %}{% fori kinderopvang in custom.kinderopvang %}
||{% input kinderopvang.naam %}|
{% newline %}
||Aantal dagen|{% $1+input kinderopvang.dagen %}||
{% newline %}
||Bedrag per dag|{% $2+input kinderopvang.bedragperdag as:currency %}||
{% newline %}
||Bedrag beperkt|{% $3+input kinderopvang.bedragbeperkt default:"11,20" as:currency %}||
{% newline %}
||Totaal aftrekbaar|{% if $2 > $3 %} {% $0+ $1*$3 as:currency %} {% else %} {% $0+ $2*$3 as:currency %}{% endif %} {{ $0 }}
{% newline %}{% endfori %}
{% endstripnewlines %}```
