Hi Francesco,
is the preview result of the  make_point(to_real(@long), to_real(@lat)) 
expression displayed in the expression editor correct?
Have you checked if the preview results of the @long, @lat, 
to_real(@long) and to_real(@lat) are correct?
What is the char used as decimal separator in the @long and @lat 
variables value?

Best regards.
