Hi @RonLevy 

1. Easiest way is to change to Choice control with the values JA and NEIN 
2. The require more effort route is to use a Quick Part formula in your Word Template 

Word Quick Part Refer here → Conditional Text In Word (nintex.com)

When the Text Substitution occurs, our variable (highlighted) will become the text “true”
Then the IF formula activates, IF “true” = “true” which evals to TRUE, with “Ja” being the output

Start Form with 6 Yes/No controls

Word Template with Part A and Part B

Test Output - We select Yes to 1,2,3. 

Hope that helps

Wonderful, @Garrett  - Thanks
