Hi Marcus, guys
firts of all thanks for your support
attached some screenshots, may it helps to understand my problem.
Tacho properties - formula.
Display properties - formula and presentation
Normally the amount of the Tacho "logistik" should be shown in red, because it fell below the 0.9.
Why it don`t recognize that the amount which is shown in the Display, is under 90 % ???
I have no ideas guys.
I would check within a textbox (should be the same like your gauge) the result of expressions like this:
bottom(sum(bew_Logistik)) // I think further you didn't need it
if(sum(bew_Logistik) <=0.9, 'true', 'false')
If this don't helped I think it's best you prepared a small example with a few inline-tables which demonstrate these issue.
