I have honestly checked over everything, and attempted to submit bids minutes later after the first failed attempts, even without another bidding. There are no spaces at the end, commas, invalid numbers or anything of the sort. I've been careful to watch what I place in the bidding area, I always am due to the fact that this keeps happening. I thought at first I was doing something wrong, but I went over every possibility and it still comes out with the error message. It didn't start until just a few days ago, and happens with a handful of the auctions I attempt to bid on. So it may just be a temporary thing, though I'll continue to do what I can on my end just in case it's where the little issue is coming from.
Thank you though for you help, I really appreciate it.
