Keine Radiobuttons?

Hallo,
wo finde ich die Extension “Radiobutton”?

There is no RadioButton control in App Inventor. You can make one. Making ‘Radio Buttons’ from CheckBoxes or try Hossein’s extension Radio Buttons . The extension might work with App Inventor.

Regards,

Steve

I downloaded the extension “RadioButtons”.
When I tried to draw the RadioButton1 I got an error message (see attaches).
