Enabling a RadioButtonGroup on a Dialog

[SirLance]

I have a RBG that I want to enable if the checkbox next to it is checked on and having trouble getting this to work.

I've tried adding Events, Arguments and Conditions to the checkbox control and the RBG but must not have the correct order or syntax.

For example, on the checkbox control I have tried:
For the Event:'SetProperty'
For the Argument:'RadioButtonGroup1'
And the Condition: Enabled = "True"

Many variations but no luck. Any help?

Thanks

RadioButtonGroup control associated with one property, then condition compares the property value.

Does RBG and checkbox are on the custom dialog or standard dialog?

Custom Dialog. I don't understand how to implement the prior responses so any help would be appreciated.
