Wrong starting auction price

[hkcdarr2009]

I mistakenly put the wrong price for item in 7 day auction I.e £2.00 instead of £20.00 Alredy have a bid @£2.10 . How do I correct the starting price , please? I informed the bidder about the mistake .

Any guidance would be helpful

You can't change it now you have a bid.  You could end the auction and relist but you will pay fees on the current bid.
