Can i recall an atrribute with a string an a macro in a function expression?

Plättenzwerg

I have multiple atrributes in pairs. The actual value and the target Value.
They are named Mi and SET Mi.
I want to create the differenz between them.
The plan was to loop(attribute) the operator genrate Attribute with the function expression %{loop_attribute} - ["SET "#loop_attribute ].
I tried diffrent functions like concat(), attribute() and the help of a second macro, but i cannot find the right expression.

Thanks for your help

Hi Hermann,

attached is a process showing this. The Generate Attribute equation I use is:

eval(%{loop_attribute})-attribute("SET "+%{loop_attribute})

I think you can adapt it from here?

Best,

Martin
