Problem with Autotrade (how i can fix this)?

Good afternoon, I have a problem with the Autotrade, everything works correctly except when buying the merchandise.

In the script commands, it only allows me to buy at least one star. (2000 pieces)

I play in a private server where a star is 500 pieces, how could I put it exactly or how to make the script to get what I see fit at any time?

Thanks in advance.

You can specify the exact quantity at the end of the command.

Thanks @Ryan for the fast answer.
