Help with Blockly NEVER MIND

[ap2017]

I have what seems to be a simple script, which does not work. I would like to set button on the screen to toggle Boolean user object variable Light_OFF (Boolean), then use script to control light. Individually all components are operational (status of user object changes, able to manually turn ON/OFF light when entering target values into corresponding object. But script does not work, What am I missing? I use script engine version 7.0.3

@ap2017 I tried the german version (same as yours), it works. Is datapoint <target_value> write : 'true'?
