Button to create new record for sub-table and with reference

Hello.

Apologize for my lack of knowledge in coding.

I have a button (Update_Storage) which is supposed to create a new record for a sub-table (History) and copy information in from another table (Storage).

While it does create the record and copies in the information from the other table, it doesn't create a reference to the current record.

Means the new record appears in the sub-table but not on the record from where I created it.  See the screenshots which might explain it a bit better than I do here.

This is the code I am using 

let myID := this;
let k := sum(Storage.Usage);
let curRec := this;
let newRec := (create History);
newRec.(Date := today());
newRec.(Usage := k);
newRec.(myID := this)

Thanks in advance for any hint.

Bernd

    Very nearly there. If the reference field for the Backup table in History is called Backup then try 

    let myID := this;
let k := sum(Storage.Usage);
let newRec := (create History);
newRec.(Date := today());
newRec.(Usage := k);
newRec.(Backup := MyID)

    There's no need for let CurRec := this as you have already assigned MyID with this value in the first line.

    Sorry, on the last line change MyID to myID.

    To take this code to the next level use 

    let myID := this;
(create History).(
    Backup := myID;
    Date := today();
    Usage := sum(Backup.Storage.Usage)
)
