I'm trying to find a certain block out of 3 blocks, using math.random
local FolderForParts = game.Workspace.Folder
local PartNumber = math.random(1,3) -- 3 Blocks in folder
local Part = --Finds the part
The part names (just keeping it simple): Part1 Part2 Part3

or FolderForParts:FindFirstChild('Folder' .. tostring(PartNumber)) if you want the naming and number to be consistent
Also a fine way to go about it, but lets keep it simple if hes unsure how to do it in the first place!
