Spawning with selected weapons issue

I have tried making several scripts which sends out values and functions to other scripts to make the player spawn with the weapons he/she selected. The problem is that the engine cannot find the weapons inside the parent object. The child objects in the parent were active but still could not be read.

The main problem in the script is found in the CharacterLoadoutScript. Where it tries to find the game object.

GameObject format

-Soldier Set (parent)
---Soldier (child, character controller)
---AssaultRifle (child, weapon)
---BlackBuster (child, secondary weapon)
---StormStick (child, weapon secondary)
