Multidimensional Table Problem

--Hi. I want to set a variable inside a multidimensional table using the entrys from a table.
--A simple example of what i am trying to do :

-- table with the keys :
local tTablePath = {"Key1", "Key2", "Key3"}

-- The multidimensional table :
local tTheOtherTable = {}
tTheOtherTable["Key1"] = {}
tTheOtherTable["Key1"]["Key2"] = {}
tTheOtherTable["Key1"]["Key2"]["Key3"] = {}

--I want to change the value of <tTheOtherTable["Key1"]["Key2"]["Key3"]> but i only have the keys in the table <tTablePath>. How can i do this?
