Color Pie chart

[Maya]

Hi everyone,

I have a problem with pie chart color  and the property : Color (by Expression)

I have my Dimension:

=if([BLN.Baseline_Number]=1,

if(round([BLN.Finish_Date]-[BLN.Start_Date])=round([PRJ.Finish_Date]-[PRJ.Start_Date]) and date([BLN.Start_Date],'DD/MM/YYYY')<>date([PRJ.Start_Date],'DD/MM/YYYY'),'Décalage', if(round([BLN.Finish_Date]-[BLN.Start_Date])<>round([PRJ.Finish_Date]-[PRJ.Start_Date]),'En retard'))
,'Planning respecté')

My measure: (who count the number of project)

=count( {<[PRJ.Statut]={'Non commencé', 'En cours'}>} [PRJ.ID])

In ther property Color: by Expression

I put exactly the same formula as my dimension but with rgb color codes.

=if([BLN.Baseline_Number]=1,

if(round([BLN.Finish_Date]-[BLN.Start_Date])=round([PRJ.Finish_Date]-[PRJ.Start_Date]) and date([BLN.Start_Date],'DD/MM/YYYY')<>date([PRJ.Start_Date],'DD/MM/YYYY'), RGB(255, 255, 0),
if(round([BLN.Finish_Date]-[BLN.Start_Date])<>round([PRJ.Finish_Date]-[PRJ.Start_Date]),RGB(249,63,23))) 
,RGB(70, 198, 70))

but it seems my expression doesn't work.

Can you help me please?

Thank you
