Re: What's being thrown away?

Nevermind. I replaced the for loop with a while loop and it eliminated the problem.

In the following snippet of code I'm getting the "useless use of a private

for the for loop.

for ($count; $count < 7; $count++) {
if ($day == '01') {
if (exists($months31{$month})){
$day = 31;
push @days, $day;
$day--;
}elsif (exists($months30{$month})){
$day = 30;
push @days, $day;
$day--;

$day = 28;
push @days, $day;
$day--;
}
}else{
push @days, $day;
$day--;
}
} # Line 64

All variables are declared elsewhere.

The only thing I can think is happening is that a return value is being expected
but isn't being provided. I can provide the entire script if needed for context.
