I try to answer without attached images (size limit)...
values are correct. I made first a virtual field in which I have "N" or "R" in
the "Colore" filed through an expression and it works. My problem is the colour
now.
I tried also with 'Colore' instead of "Colore", but nothing change.
Here the code:
CASE
When
get_feature('V_TB_ATTIVITA_PT_NR','Colore','N')='N' then color_rgb (0,0,0)
When
get_feature('V_TB_ATTIVITA_PT_NR','Colore','R')='R' then color_rgb (255,0,0)
END
I'm pretty sure that in expression.... 'V_TB_ATTIVITA_PT_NR','Colore','N'...
'N' does not have sense, but I don't know what to pu... sorry, but I'm a super
beginner with code :(
Cheers
