Expression Designer syntax error, Why?

Variable x: Number
Variable y: Null

This is exactly as in GH Primer V3-3. Still paralyzed by “syntax error” message.
Now I use GH 1.0.0007. Maybe something has changed in this newer GH version? Any clue?

It would be good if you add a screenshot if not the gh file. (12.0 KB)
