<p>Hi Dario,</p>
<p>Could you try with 'Colore' and not "Colore" (pay attention to
the simple vs double quotes)?</p>
<p>Regards,</p>
<p>Harrissou<br>

<div dir="ltr"> Hi, thank you for your reply, but I still don't
understand how to do... sorry
<div><br>
</div>
<div>i tried to write this code in colour expression, but I
don't understand what "value" is in get_feature
:</div>
<div><br>
</div>
<div>CASE<br>
When<br>
get_feature('V_TB_ATTIVITA_PT_NR',"Colore",'N')='N' then
color_rgb (0,0,0)<br>
When<br>
get_feature('V_TB_ATTIVITA_PT_NR',"Colore",'R')='R' then
color_rgb (255,0,0)<br>
END<br>
</div>
<div><br>
</div>
<div>Consider that I have a virtual field called "Colore" where
I have 'N' or 'R' in case it is black or red color.</div>
<div><br>
</div>
<div>Thank you for your kind availability.</div>
<div><br>
</div>
<div>cheers</div>
