Correctable or not??

[ref18]

Today I had some rec-league games. Near the end of the first half my partner calls a foul on B1. We administer the throw in and 20 seconds later the buzzer goes to end the half.

At halftime the scorer comes up to us and tells us that it was B's 7th team foul.

Now because we're still in the first dead ball after the clock started following the error is it correctable??
