Because the locations of sub.pl and variable.pl are not being found by Perl. When you require a file, Perl looks inside the @INC array and tries to find files in the only 2 paths it has: C:/indigoperl/lib and C:/indigoperl/site/lib. If i were you, i would find the full path to the directory that contains those two files and add the following line BEFORE you require those two files:

use lib '/path/to/my/files';
[download]

Or, if that doesn't work:

push @INC, '/path/to/my/files';
[download]

You will have to replace that string with the proper path, of course. Please don't ask us what that proper path is, you will have to figure this one out. (hint: it's the full path of the folder that contains those two files that you want in include.)

And please, dude. The word is why, not whay. I told you this once before. I get the feeling that you aren't listening ...
