Forum Payment method (donation)

[narutosx]

Hello, so i have on me a Neosurf code of 15€ that i would like to use in order to have the premium account , but the problem is that when i go to donate choosing (Neosurf) method i can't find the 15€ spot i see only 10/20/30.. so can i in this case use 15€ in the [(10€)10coins] one even if i loose 5€ it doesn't matter or it won't work and thanks in advance

Cheers.
