Hi. New poster here! I'm building a Cricket Sports Database. The code below runs fine until it gets past batters who have scored runs, (returns 236 records) but when it hits bowlers with no runs (blank Field), I get Division by Zero error. I've tried allsorts of solutions ... mainly from here; but I'm a bit new and can't figure it out... It's a flat file system DBMan from years ago; but still great if working!! I've truncated the table for easier viewing...


sub html_record {
# --------------------------------------------------------
my (%rec) = @_;        # Load any defaults to put in the VALUE field.
    
$total = 0;
$total = $rec{'BatterRuns'} + $rec{'HighestScore'};

$baverage1 = 0;
$baverage1 = $rec{'Innings'} - $rec{'NotOut'};
    
$baverage = 0;
$baverage =  $rec{'BatterRuns'} / $baverage1;    

# Gives 236 correct results until it hits a blank bowler field 
# who has not batted ie: NULL</b>
    
($db_auto_generate and print &build_html_record(%rec) and return);
  
   
print qq|
