Only 1 out of 9 when you buy currency in my game works, why?

It is supposed to work like if you press a button and pay the robux you get the currency, in this case "Bits". For some reason only the first one works "250 Bits". The buttons work but when you have pressed the buy button you get no bits. I can not even see that it printed in the output. Only the "Two_Fifty" one, that's the only that works. Why?

Thanks for the help, if you need more information, just ask :) , Xsodar

Addendum to my comment.

Also you should use elseif instead of so many ifs, like so:

But I'm not familiar with the marketplace so maybe it won't work like this.
