However, I did use in script.pl , it s okay.. it works..

Please help and thank you very much

You probably simply miss the "1;" at the end of the .pm file.

Perl modules always have to return a "true" value. This is accomplished by simply putting "1;" at the end of the file.

More information can be found in the example code of Perl Modules in the perlmod documentation.

"Compilation failed in require" indicates compilation cannot continue beyond that point due to an earlier error. Solve the earlier error and this one will go away.
