Ok.. I understand...
I found this thread concerning almost the same problem:
http://www.typo3-jack.net/typo3-project-templavoila-lists-netfielders-de/7955-typo3-templavoila-fce-image-checkbox-select-if-clickenlarge-lightbox-not.html

but does this mean you only can use HARDCODED values, if the data type is  
string?
As I understand there isn't even the possibility to set variables within  
TS...

It's very frustrating having high ambitions and using TS :-(
