The calculated field does not work in my form as well as the creation of a unique number for each household

Hi
Let us start with the first part of your issue

@esy_cari2020

I followed your advice and recommendations offered on the forum, but when I launch the overview test, it shows the following error that I cannot correct namely: {There has been a problem trying to replace $ {Quelle_de_Gar_ons_f_nt_la_classe_de_CP2_} with the XPath to the survey element named ‘Quelle_de_Gar_ons_f_nt_la_classe_de_CP2_’. There is no survey element with this name.} And this is the same for all school levels (CE1, CE2, CM1, and CM2) as well as all the other parts in yellow where I want to perform the calculations.

You need to download the XLS version of your form and closely inspect the form to see the incidence where you have referenced a question/varriable which does not exist. Check for any spelling mistakes. This is a form design issue and not a system issue.

$ {Quelle_de_Gar_ons_f_nt_la_classe_de_CP2_}

On the second part of your query, and as you may have realized, this is not a provided functionality for form designs. You will need to create this based on your need. See a sample of what you can find when you search for discussions: You can also see a more relevant discussion here:

Creating unique ID from the available variables using calculate

I have made a unique id by using note. [uniqueid1] [uniqueid-form] But this note value is not going to the server. [uniqueid-xls] So actually I want my note value will go to the server (with “/”), like this picture. [uniqueid-actual%20I%20need%20this] Thank You.
