Can't use the command IsDefined on a "multivariable function"

Not a Problem

It seams it isn't possible to use the command IsDefined on a "multivariable function", as I get the result "true" although it says "= ?" in the Algebra window.

Could you please make it possible to use the command IsDefined on a "multivariable function".

In the meantime, can I get a workaround solution ?

Sorry.

When trying to create a simple example, it works (se the attached file).

So I must have done something wrong in my other applet...

My other aplet was created in an older version of GeoGebra.

In the newer version there isn't any problem.
