I understand it but the bar shows 112mln. and 1 token, I have 6 tokens so I should move the bar till I am out of tokens but I can't move the bar at alle.
ok, if you 've done the calculations as the example and you 're ok, then it's another case.
When the player you made an offer, for some reason is out from negotiation list (fro example he got 1 sp if he played a game or he got the sp gift from friends), then the game sometimes "reacting" like there is a bug. It doesn't inform you that the player isn't available for buying anymore.
Anyway, 24h past so you can tell us if you still can see him in nego list.

but
an advice from me. As I see you don't have much T so I recommend not buying from nego list those days.
We 're near the end of the season and if you promote to the next lv, this player is gonna be an early 5* player for the next season.
If you won't promote, wait a little and check the market many times every day.
This period, many managers selling lot of good players to get read of them before the next season.
I also selling many good players with extra position or sa this period, after finishing some semi or finals.
Sometimes with a good discount and without many people to bid.
