Hi @agdali
You should read again the rules about "participating into the guesstimate contest" or you can visit the older post of "Garage Sale Issue" to see a participant can guesstimate once when She/He bid. I think you misunderstood something.
If i made a mistake about entering in to the contest or break any rules, i think Sir @BabsBoard & @EveryDayCoach would have already point out the mistake.

Thank so much @gentlebot for giving me an @upvote.
