Accessed none trying to read property from function

Hi Everyone,

Been scratching my head at this error for the last few hours and cant seem to figure where it stems from. thought a fresh pair of eyes looking might be able to solve the problem.

it looks like my master weapon blueprint is returning as null? do i need an is valid node somewhere, or have i not spawned the weapon correctly?

Thanks for any help!!

You gave 4 screen shots and the ONE thing that is causing the problem is cut off haha Can you take a new pic of what is below the highlighted area?
