Perl Cannot Find/Reload File - html

Question

I have a submit.html file that prints calculations done in a file called Observation.pm. Observation.pm exists in the folder called project. However, when the script runs, these error are printed:
Error during compilation of submit.html:Attempt to reload project/Observation.pm aborted.Compilation failed in require at submit.html line 67.
Line 67 in submit.html is:
use project::Observation.pm;
For some reason, it cannot find the Observation.pm file.
I have tried deleting and adding the Observation.pm file again. I've also tried using
use lib /path/name/to/project/;
in submit.html.
Any ideas on why this is happening or how to fix it? Let me know if I left out some vital info of the problem, wasn't sure what was relevant.

Answer 1

Try to use: Observation::Attempt instead of Atempt and also use path to the .pm file

Answer 2

When you use project::Observation;, Perl looks in #INC directories, if it finds an appropriate module.
In your case (use lib '/path/name/to/project';), this means it looks for a module named /path/name/to/project/project/Observation.pm.
Note the double .../project/project/.... So the correct search path must include /path/name/to instead, e.g.
use lib /path/name/to;
or if you want/need to keep use lib '/path/name/to/project';, say
use Observation;
instead.
Also note #ChrisTurner's comment, don't add the .pm extension.
