Why can my script not find some folders under ServerStorage?

I am trying to code an ability system. When the player first joins, I create a folder inside a folder inside of server storage. This folder that I just create is named after the player.

ServerStorage -> SelectedAbilities -> Player one

In a script stored under ServerScriptService, I try to call upon it when the buttons "Q" and "E" are pressed. Here is my current code for when this happens.

local selectedAbilities = game.ServerStorage:FindFirstChild("SelectedAbilities")
local plrObject = selectedAbilities:FindFirstChild(player)

abNumb = plrObject.Ability2.Value
ab = abModule.AbilityReturn(abNumb) 
print("Ability2 = "..ab)

The issue is that plrObject, the variable, is returning nil causing the script to break.

I confirmed the variable player to be equal to the player name. I have also confirmed selectedAbilities to be the correct object. Because this script only activates after a button is pressed, the likely hood that the objects aren't loaded in is about zero. I will continue to look into this and keep this post updated but any help will be appreciated
