Invalid entry. Just like the last time, same reason. But you don´t read the posts, nor the replies...

My bad
I felt my $0.45 should still be the same as $0.4500
Can I update it?

There are only 3 simple rules here. One of them is:

"Round your guess to 3 decimal digits (for example: $0.456 or $0.800)"

Another rule is: "Only one guess per person, no editing."

So no, you cannot edit it, you need to be more careful next time. But seriously, why you seem to always comment without reading the actual posts? Many people downvote such behavior...
