Hello,

I would like to show the current quota in some text. Is there maybe some expression to do that?

Maybe like this: {completeCount} / {qlimit}

Currently quotas are not accessible via EM(Expression Manager).
You might open a feature request or provide support for existing feature requests.

What version of LimeSurvey do you use?

Too bad!

I am using Version 2.72.0+171010
