Why will this welding process not work?

I have this script that should cycle through a list of body parts (In a rather clunky manner) And weld a set of parts to the specified body part. However, When the script is activated, Nothing Happened

local OB = PlayerAttire:WaitForChild("OutfitBottom")

Previously, this line used FindFirstChild which resulted in OB coming back as nil. OutfitBottom is a StringValue within a folder named Outfit.

Sorry for the gross code at the bottom, I'm gonna put that list of body parts into a table or something. Thanks for any help!
