Question regarding transform formula. I am trying to get the over/under speed indicator displayed. I set a variable (#) that equals 1 for overspeed "B", 2 for underspeed "A"
When trying to use this formula below it fails, when leaving the second if-clause out, no problem. Multiple if-clauses not allowed? Any thoughts on how to do it differently?

if(#=1,'B'+$,if(#=2,'A'+$,$),$)

It should work.... But you would need a Left Padding Space OR you would need to use a "Space" in case if non Over or Underspeed is On.

Your issue in the quoted Code.... You got one ,$ to much....

Yours: if(#=1,'B'+$,if(#=2,'A'+$,$),$)
Correct is: if(#=1,'B'+$,if(#=2,'A'+$,$))
Syntax is ... if(Indication1,THEN,if(Indication2,THEN,ELSE))
So the initial IF not have a own ELSE.... Cause the second IF represent the ELSE of the first.

I´m for now not 100% shure whats the best Syntax..... Also NOTE: We did a segnificant change here.... Its recommend to use MF 9.6.0.5 BETA here. Some Issues come into System with 9.6.0 We already fix in the Beta.

i would use for testing: if(#=1,'B$',if(#=2,'A$',$))

To include the "Space" you can simply add a Space next to the last Dollar.... Cause without Over or Underspeed the Digit must be Empty.
So.... if(#=1,'B$',if(#=2,'A$',' $))

Much more straight forward would be to do the B-A-Space already in the Config where you read it....

So in that Config you could say .... if($=0,' ',if($=1,'B','A'))
Then you must use in the Display config only placeholder # for the refference to other Config and you say in transform '#$'
