Remarque & FAQ

I tried to submit an application, and it failed to submit (but I'm not sure if it is failed or not). But I already paid at this stage. So I tried second times to submit. But I already paid at the first try before, so I didn't pay for the second time. for summary, 1st try : submit (x), registration fee (o) 2nd try : submit (o), registration fee (x) Can I check if my application is submitted with registration fee successfully?
