I am trying to make two boolean gadgets mutually exclusive of each other
The code below works ish. When the first gadget is selected, it is highlighted.
When the second gadget is selected, it is highlighted and the first should
be un-highlighted as a toggle where one or the other is highlighted, but
not both. 

At the moment, the second click on a gadget cause it to change its colours.
Any help on this would be apreciated.

I believe that to do this, the gadgets have to be removed, altered and then
re-added to the window, is this true?

The code below is taken from a program and is from the code for handling
the GADGETUP message. PURCHASE and REPAY are both gadget structures.

			} else if(Message->IAddress == (APTR)&REPAY) {
				PR = PR_REPAY;
				ip = RemoveGadget(AddWindow, &PURCHASE);
				ir = RemoveGadget(AddWindow, &REPAY);
				REPAY.Flags |= SELECTED;
				PURCHASE.Flags &= ~SELECTED;
				AddGadget(AddWindow, &PURCHASE, ip);
				AddGadget(AddWindow, &REPAY, ir);
				RefreshGadgets(&REPAY, AddWindow, NULL);
			} else if(Message->IAddress == (APTR)&PURCHASE) {
				PR = PR_PURCHASE;
				ir = RemoveGadget(AddWindow, &REPAY);
				ip = RemoveGadget(AddWindow, &PURCHASE);
				PURCHASE.Flags |= SELECTED;
				REPAY.Flags &= ~SELECTED;
				AddGadget(AddWindow, &REPAY, ir);
				AddGadget(AddWindow, &PURCHASE, ip);
				RefreshGadgets(&REPAY, AddWindow, NULL);
			}

many thanks.
