Dynamic inputs to add rows in another table

[INN_ENGENHARIA]

I have been trying to use the expression input() to add rows to another table, but it seems that the dynamic input is not recognized, as it is my first time using this fuction, i dont know if i’m wrong or as it is a beta fuction it is not working as it should.

1. First I have created an action to add the rows to another table:

2. Then i have put an expression to call the dynamic input from the parent table:

3. Last i add an action to execute from the parent table and declared the input “id orçamento” to be the value from the row [id orçamento]:

Result:

It has been a wild ride to put this function working, if anyone could help i would be much obliged.
