Hi everyone,

I am trying to calculate the fields and add the sum of values into the other field. Unfortunately it does not work. I am new in Modelbuilder so maybe it will be a simple trick how to change it...

I hope it is no problem that the schema is in german.

I calculate a sum of length from Layer "Trassenabschnitt_eigen" and Trassenabschnitt_angemietet". Through the "Get field value" (Feldwert abrufen) I get the result of summary. I need to get the sum of both this summaries (due to "Calculate Value" =Wert berechnen). Till this point is everything ok... 

Maybe the "expresion" (Ausdruck) is not correct? Because when writing the Value into the Project_Auszug Layer, the Value is "1".. not sure what doing wrong.

Thanks for any help!
