WeiDU Help With: How to alter items from an existing container and add an item to a creature?

Hello I am trying to change the container items within the chest in AR5405.ARE to be as this: What command does one write in the .tp2 file to instigate this change to Container1 in AR5405.ARE (Mulahey's Lair)? Also how does one add "OLRING06" to Mulahey ("MULAHE.CRE") without breaking him for other mods? COPY_EXISTING ~MULAHE.CRE~ ~override~ ADD_CRE_ITEM ~OLRING06~ #0 #0 #0 ~NONE~ ~RRING~ ? Source: https://www.weidu.org/~thebigg/README-WeiDU.html#sec34 This is for an Original Baldur's Gate Module 'Xan's New Groove': I am none too good with operating WeiDU :-P. Any help would be great to get this to launch soon. @Arunsun
