in the "List & Search Type"-Area i have build a list with items and set with button 2 an choise "Form" a link in every itemname to have the possibility to edit every item.

But when i use after a click on + in the area construction1 as Content Type (Form) inherited of this formlink as choise i have a false Form BUT the correcgt id of the item in a domainstring.
When i set the Content Type (Form) to the correct Form, i have a domainlink to the correct Form BUT NOW i lost the associated and needed Item ID and have an empty form.

What i can/must do to linked to the correcht item? How i can find and set the item id?

I try this in the custom Variables - Field, but its work only when i hardcoded it as "id=12". I need a variable. ow i set this correct?

I search the last 3 hours but all information abaout this theme write abaut <php> - Code....
