Pay Pal Integration Is Not Working

Hi rajendra.

Since you (rightly) installed lm_paypal, you shoud look for documentation and help in that project, not paypal framework (which is a different project).

By the way, your question was too vague ("it don't know how to use it"). I encourage you to first read carefuly the documentation at http://drupal.org/project/lm_paypal and in the module's file, and if you need help to explain precisely what you want to achieve, what you tried and what didn't work as expected.

Cheers,

Daniel
