Hi @flugan87, the @Value function should starts with uppercase V.
The SQLExcutor might work after correcting the function name, but I think using the FeatureReader (set 'Contain' to the Spatial Filter parameter) would be easier in this case.
Try the FeatureReader rather than the SQLExecutor. You can send the municipality polygon to the FeatureReader and it will automatically filter the features using the geometry.
