Hi Paul,
Think some more about this counter, I think you mean 'successes' as in
'successful attempts' than 'successful test' ? If so, then perhaps you can
drop this patch. It wasn't clear to me what the 'successes' meant so I may
have been a bit misled into changing its meaning. If on the other hand, it
means 'successful test', then yes this patch would be Ok then. thanks! -Joel
