How to implement logical structure in Radio Button Group with GUI

Hey Guys,

I am new to GUI Programming and i implemented a Radio button structure as follows:

now i try to implement a logical structure in there. I want the 'Local' Checkbox to be inactive first. and then i want it to be activated as soon as there is any of the 3 options of the radio buttons activated. There can be activated all 3 radio buttons, so it is not exclusive. But as soon as no radio button is checked, the 'Local' Checkbox shall be unchecked again too.

I tried to do it like this

if (handles.onlypvdroop_control==1 || handles.onlyunbalance_control==1 || handles.onlylala_control==1)
    set(handles.local_control,'Value',1)
else
    set(handles.local_control,'Value',0)
end

this doesnt give an error but doesnt work either.

What is the problem, HOw can i make it work?

I am very glad for your help Best regards, busta x

busta x - your condition is comparing the handle for each radio button to 1, and not comparing the value of the radio buttons. So something like this would be the correct form for your condition

 if get(handles.onlypvdroop_control,'Value')==1 || get(handles.onlyunbalance_control,'Value') ==1 || get(handles.onlylala_control,'Value')==1

The above will only fix part of the problem though because of your requirement that all three radio buttons can be activated or that all radio buttons can be unchecked. If you have a group of radio buttons (like you do) then exactly one should be set/on at any one time and never more than one (this is typical radio button behaviour). If you want to allow the user to turn on more than one or have all of them off, then you should be using check boxes instead.

Thank you so much Geoff! I see the mistake!
