Dynamic Component Text string with - and / slash and dash

Hey Community,
i am trying to build a dynamic component, with the functionality do display some text strings, depending on a selection in a pull-down-list. Unfortunately the text string has slashes and dashes and it does not work…I tried with concatenate () but it doesn’t work too…and i tried with " " or with ’ '…no chance… mmmh
I’m up to do this:
Thanks a lot 4 your help

Choose (optionindex()) expects a number for input and then it chooses from the array of options.
The first is a concatenated one , the others don’t have quotes.
Can you share an example?
