Searched many but cant figure the problem out here..

Answer 1

I presume you environment requires , as separator and not ;

If you just do =Aktif and it works and =Baslik (with that special character s) does not,

Then I think the problem is the DisplayName.. you can easily try by changing the displayname to a normal s
