How to enable convert option for non administrator user

Hi,

  I'm  facing a challenge while giving permission for convert option for non administrative profiles. I have some custom modules, in that some custom convert functions are there.(Operation: if any one click the convert button, that perticular record will move to another custom module).

    And I have four active user's including a administrator. Here the problem is other then administrator user coudn't perform this convert action. So that I have tried to give permission in module permissions.

In that convert permission option described like " Only modules with view permission are listed here for convert.". So I enabled View permission for all custom and default modules. But there is no custom modules are listed in convert option, Only defaults modules are there (ex: lead, sales). We need to give permissions for custom modules (Ex; interview, shortlist).

   So please help me to going forward with this, for more clarification please look into the attached screenshots.
