Monks,

I've been agonizing over this problem for a while...

I have this database and I need to calculate the average of the values in a particular column (that value is $temp1[38] in my array). The calculation of the average depends on one criteria;

for all the rows if $temp1[36] = "In Production";

then I would take those rows $temp1[38] values and calculate their average. Does that make sense?


Here's my code so far:

#!/usr/local/bin/perl5
print "Content-type: text/html\n\n";
open(HANDLE,"script_integration_records");
while (<HANDLE>) {
@temp1 = split(/:/);
$domain = unpack ("A4", $temp1[40]);
if ($domain eq "ATM") {
   if ($temp1[36] eq "In Production") {
      print "$temp1[38]\n"; # This is my break point...I think here's 
+where I need help
      }
   }
}
close(HANDLE);

The output of this code works, but it just does prints out a list of values that is in the array I have...the values are correct, I just need to take those values and find their average. Here's the output:

34 114 123 2 5 48 71 67 71

Thanks so much for enlightening me!
