Unsuccessful sniper bid even though I had the highest bid by more than 100 yen

I got this message after I placed a sniper bid. It was the higest bid, and it seemed to have went through.

"Thank you for using Buyee. Although, we tried to bid on the auction before the auction ends, your bidding amount was not higher than the minimum bidding price for this auction. Therefore, unfortunately, we could not process your sniper bid successfully. * Due to JDirectItems Auction' policy, the minimum bidding prices are not shown before bidding. "

How do I confirm if I won or lost?
