Help! Problem with Form List

[dider103]

I like effect of Ulysses' Duster but I don't like its appearance, so I made an armor for myself. Also I installed the Signature Armor Mod, so basically what I trying to do is adding my armor to my character when he reaches a certain level, meanwhile add this armor to the Sgnature Armor formlist in order to use this armor as my signature armor.

Here comes the problem, when I use the addformtoformlist function,

player.removeitem ThePreviousSignatureArmor 1
player.additem MyArmor 1
player.equipitem MyArmor
AddFormToFormList SignatureArmor MyArmor

(well don't mind the name, I changed them)

without the last line, the script processes successfully, but when I add the last line, my armor is not even added to my character. I guess it might because the "signaturearmor" formlist is in the other mod so I cannot add forms to it? In case anyone ask, I did check the "SignatureArmor.esp" when I load the files.

By the way, is it possible to use two esp files to get two signature armors? Will there be conflict?

Any helps? Thanks!
