Passing hidden variable from collect to aggregate

[Saad]

Is it possible to pass a custom hidden variable from Collect to aggregate, other than the fixed ones (IMEI, sim number, etc)?

Thanks,
Saad

If you use calculate type questions they are, in a way, hidden. There's the audit log functionality. Can you please explain desired use case a bit more?

Can the form version be accessed from inside the form?

To build on @LN , a slightly more general purpose solution to getting the form name and form version from 'inside the form' is to use the XPath expressions: form name: /*[1]/@id form version: /*[1]/@version You can use these expressions anywhere, eg calculation, relevent, required, ... In case yer curious, the first / selects the document root, the *[1] selects the first node under it (which will be your primary form instance), and the @id and @version give you the corresponding property val…

Great, thanks! It works fine.

Is there a list of all variables which we can send through this method, other than form id and version?
