Hi Matthijs

Do you mean something like this?

{{ $2-$1-1 | integer }}

Kind regards  
Sam

Right, forgot about that for a second.  
You can solve it by doing this.

{%=$1+input custom.dieselpw.begindatum as:date %}  
{%=$2+input custom.dieselpw.einddatum as:date %}

{% assign beginDate = custom.dieselpw.begindatum | date: ‘%s’ %}  
{% assign endDate = custom.dieselpw.einddatum | date: ‘%s’ %}

{% assign diffSeconds = endDate-beginDate %}  
{% assign diffDays = diffSeconds/3600/24 %}

{{ diffDays | integer }}

Let me know if this solved it 😃
