I would like to filter on a part type page (listpage) based on the chosen field on card page.
On Cardpage: I put the chosen value into a global variable.
I want to use this global variable to filter the content of the subpage, and see only datas in connection with the chosen card page field.
But! I can not see the variable from the cardpage, and i don't know why.
How should i do this?
How to send variables between pages?
