How are you?
I'm currently having a problem scheduling an IS match against my opponent. We have agreed to play on Saturday 12 July at 8pm and are both available at that time. However, the script is refusing to validate this schedule, saying that I won't be free, which is incorrect.
What should I do?
Thank you in advance.

Is your opponent free?
No match scheduled or federation?

michbou: Ton adversaire est libre ??
Pas de match de programmer où fédération ?

Yes, he's free.
No programme matches

Try again tomorrow morning (as soon as it works)

Okay, thanks!

By any chance, did you initially suggest a different timetable, which he didn't agree with?
