How much is it? NL all-in amount ruling

[ToDissemble]

I just double-checked with Bellagio on this one

A) Regardless of player's answer, you are responsible to call the full amount of his allin, or obv whatever amount you have on table up to that amount.
B) You will be held responsible for calling the amount verified by the dealer. If the dealer makes a mistake it is obv not your fault and you will only have to call what he stated as the amount.
C) same as situation B

I would like to add that although this is the rule at the Bellagio, I have been held responsible for an allin call at the Orleans Open in an PLO game even after the dealer told the floorperson he told me an incorrect bet amount. So it is a good idea to wait until the dealer breaks down chips and/or bill packets before stating your intent if there is any doubt at all.
