php email form issues with callback module

I have an existing module we wrote that is having conflict with a callback module which during certain circumstances emails r sent blank. If client selects callback and sets a reminder , then calls the contact and completes interested form then sends it to upline sales agent, the form arrives blank. So we figure when the data is referenced into the callback module we wrote, it is no longer the same variable name/etc and is not included when form is emailed when having used the callback reminder. Please Note: Only access to folders with modules with be allowed, no root access. We will assist in all procedures that require root access or other folder file adjustments.
