`==` is for numeric comparisons; you mean `eq`. Go read perlop. Additionally: It doesn't really make any sense to close your output handle and then go on to process more rows. You probably want to use last to exit the loop and then close and print your footer outside. The cake is a lie. The cake is a lie. The cake is a lie.	[reply] [d/l] [select]

"What is the mistake here?" Again, no: `use strict; use warnings;` [download] See Use strict and warnings, Use strict warnings and diagnostics or die and How do I post a question effectively?. Didn't you post this already as Question on the format statement?	[reply] [d/l]

`if ($subdvn=='KP' && $tow=='RP' && $phase=='1' )` Probably that you are using numeric == to compare strings. Of course, if you use strict & warnings, you'd now that already.	[reply] [d/l]

By the way there is no 'if' loop. `if` is a branching construct, not a loop. You can also say 'if' statement.	[reply] [d/l]

Try if ($subdvn eq 'KP' and $tow eq 'RP' and $phase eq '1' ) instead of if ($subdvn=='KP' && $tow=='RP' && $phase=='1' ) Krambambuli ---	[reply]

What is the mistake here? You keep doing the same thing and expecting a different output.	[reply]
