Hello together i have a little tricky problem in PowerAutome. I am creating an App and i will show you the pictures for the understanding

As you can see in this part in the picture i have a radio field and a combo field
in both field i have in the default part a variabel

default value for the combo box
default value for the radio field
in another screen i initializat my variables.
In this screen the person (ink-series for the radio button) the people choose their series

and in the next symbol i make the initalization for the formular

for the substrate with the combo box i make the same

now my problem is for the radio field i see the choices the users make in my other screen and i have no error but for the combo field i get an error

I geht this error message:
Recorder value expected
Record values are expected for the property for this control element. The rule generates text values that are not compatible
Where is my mistake?
