Can anyone check the correctness..?

We had a competitive match on Tuesday with SCF . Unfortunately we lost by 7 wickets, but all performances were satisfactory.
We just started scoring with the proper scoring application for this match. The last match report is attached with this email for your reference.
I am really happy to inform you that we are registered for our first tournament at QAC. There are 16 teams participating in this tournament so it will be a great challenge for us.
