How to display subtable of subtable on master table form?

Folks.. Using the project template database as an example, if I add mulitple sub projects to the sample Garden Design project.. and add multiple tasks to each subproject,  how would I build a view layout element that displays all tasks assigned to a project?

allTasks

    OK.. I figured it out.. Not sure why it did not work before..  Here is the view / formula..
    (select 'Sub Project').Task
    allTasks

    Well.. only partially figured it out.. Still need to work on the filter / where clause.

    Well.  I got stuck again..:(    This will give me the tasks only for Projekt.Id of 2 .. which is Arina's Pool.
    (select 'Sub Project')[Projekt = 2].Task

    What I am having trouble figuring out is.. How do I reference the Id of the currently visible / selected Projekt row??  I have tried. 
    (select 'Sub Project')[Projekt = Id].Task
    (select 'Sub Project')[Projekt = this.Id].Task
    (select 'Sub Project')[Projekt = Projekt.Id].Task

    this worked for me where I wanted to show order for a specific customer: select 'Tasks' where Project.Id = (input the project's id) That's rather manual, but maybe this would work: let theid:= id select 'Tasks' where Project.Id = theid

    Thanks Stephen.. I did figure out to use the Select statement. and Yes.. If I hard code the Projekt.Id .. it works.. What I am trying to figure out is ... If I am currently positioned / viewing the Projekt Record that has Id 2... When I add a layout element of "view" ... this.Id should be 2.  Putting that in my formula does not filter to the proper task rows.

    OK.. Will do.. but it is pretty simple.. Using the Project template database... Add a view of to the Project form.. I want to display Tasks associated to the seleced project (via the projects sub projects)..  I will email the database.   I suspect I do not understand how the links are working. :(

    OK.. Got a reply from support..   THANK YOU FOR PROMPT REPLY!  AWESOME!

    So... I was all around it.. The part I missed was the data type of "Id"..   Here is their reply..   I highlighted the key! ;) 

    Try it like this:
    - Open the Project form.
    - Swtich to Admin Mode.
    - Select the properties of the 'Tasks' view.
    - Change the formula like this:
    –––
    let myID := number(this.Id);
    (select Task)['Sub Project'.Projekt = myID]
    –––
