Wire.requestFrom correction on webpage

Hello,

Thanks for your site! It is very useful.
I was learning about Wire.requestFrom() from your discussion/posts.
On the page
http://gammon.com.au/forum/?id=10896#i2csummary
About in the middle it says

But the example after that appears to have the logic reversed. "handle error" would occur if zero was returned, but your condition is not... notted?
Or just swap the comments and its good.
Or maybe I'm totally confused!

Thanks,
Skippy

You are right, I got that backwards when doing the summary. I changed to compare to zero to make it clearer.

Thanks for letting me know!
