Problems with "conditional logic"

Hello, i have a problem with the conditional logic of my form, but I can't find the mistake.
In my form I have a radio group with 4 options (The field called "Ich benötige")
If no one of the 4 options are choosen, the next 5 fields are hide.
If the first option are choosen (Fliesen für Innen), only field 1,3,4,5 should be shown.
If the second option are choosen (Fliesen für Außen), only field 2,3,4,5 should be shown.
If the third option are choosen (Fliesen für Außen), field 1,2,3,4,5 should be shown.
If the fourth option are choosen (Fliesen für Außen), no field should be shown.

I tried lots of conditional logics, but it doesn't work yet.

Please help me.

Best regards
Markus
