In this case, you don't need the mvars.  Let sum() do the iteration:

        for-each ($neighbour-list/bgp-peer) {
            <output> jcs:printf("%-20s%-15s%-12s%-10s%-10s%-10s%-10s%-5s",
                peer-address,
                peer-as,
                peer-state,
                elapsed-time,
		sum(bgp-rib/active-prefix-count),
		sum(bgp-rib/received-prefix-count),
		sum(bgp-rib/accepted-prefix-count),
                description);   
        }

Thanks,
