I have several checkboxes that I want to use, and if one checkbox has a selected value of True, I want the other ones to all be false.

The current logic I have is this, on propertychange:

```auto
'Logic for first checkbox
if (event.source.parent.getComponent('2ndChk').selected == True):
	event.source.parent.getComponent('2ndChk').selected=False

'Logic for second checkbox
if (event.source.parent.getComponent('1stChk').selected == True):
	event.source.parent.getComponent('1stChk').selected=False

```

I’m thinking I should be using the newValue features, but I haven’t been able to actually access them

This seems like a job for a [Radio Button](https://docs.inductiveautomation.com/display/DOC80/Vision+-+Radio+Button). Groups of radio buttons are designed to be mutually exclusive by default.
