grouped buttons-activate one switch off the rest

Hi, I have a couple of buttons grouped and want them to behave in such a way that the active button is switched on and when I press another, the former goes off and the active goes on. It gets pretty confusing having multiple buttons on and lit on the lemur, while only one is actually active on the software.

Any ideas how to solve this? Thanks!

Hi
If you use switches then you can select 'radio' in the properties and it will behave how you want . ..
