There is nothing obviously wrong with this code and I gain no new insight from reading what I presume was the previous node in this thread, Query Array from Hash. Please give some sample input data, or even better the output generated by Dumper (Data::Dumper) so we can compare the data structure you have to the one your code expects.

The my is localizing your result to the implicit for loop. Try this instead: 

my $sumcredits = 0;
for (@trans_details) {
    $sumcredits += $_->{'credits'}
}
