change "panel.cellradioid" by scripting


Absolute beginner here.

I am trying to change the cellradioid panel value of a radio button group using an Execute DAT but can’t figure how…
I think I should write:
op(“nameMe”).panel.cellradioid = x
but I can’t understand which operator in the table is the target…
I am using several presets manager gadgets and want to make them switch together using a button.

Hope it’s clear…

Any help appreciated.
