error2103: problems while saving files using an emulator

i recently built an app which uses the save file component, but when i made the app save a file, there was an error:

"Error 2103: the file /mnt/scard/puddingservice/akt_guthaben could not be created"

Here a screenshots of my blocks:

What can i do to fix the problem? I would be very glad if someone here could help me.

the file component can't create directories, which means, make sure, the directory puddingservice exists...

btw. the canvas component can create directories in case you need this...

Thank you for your fast help, i will try that!
