I was using a . not a , (comma). I also tried a whole number (for example $100) without a decimal. I just tried a "," to see what would happen and it just returns an error:

I will wait some more and see if the server works later. Thanks for the answer Jaxs.
On the first day after the IPO, the shares have a “wrong” price. The price of a share in AirlineSim depends of the book value of the airline. And you may only pay +10% or -10% of the price that depends on the book value. So try it with prices around 100 AS$. That should work, I just tested it
