Having just spent a frustrating half an hour being given the run round on their website i give up !Trying to get phone number for customer support anybody know it or do i need a pin number as well ?The problem is still this .When i complete the for sale listing it keeps asking for a valid value .This is at the top of the page in a red rectangle with a red warning triangle .Problem is i can’t find the section that i need to change !

Can you post a screen dump?

Long shot, are you putting the zeros in the price, that’s what happened to me when I put £50.00 instead of £50, took the zeros out and it was fine
Took a while to work out though 😳
