I followed the creation kit tutorial for adding a custom weapon to the game. I'm talking the simple one where you duplicate an existing weapon, change the damage and crit value, change the ID and name and then save your .esp. It loads in the data files menu, where it is checked, but when in game trying to - player.AddItem DovahkiinSword 1 - I get an error saying that

"Item 'DovahkiinSword' not found for parameter ObjectID

Compiled script not saved"

Did I miss a step?

I also tried it with armor, with and without the quantity, tried using player.equipitem, all with the same result.

When using the console, you have to use an 8-digit hexadecimal code known as a formID instead of an editorID, which is the human-readable ID assigned to an object in the Creation Kit.

To easily find formIDs, which vary slightly depending on your load order, use the http://www.creationkit.com/Help command:

Help "Dovahkiin Sword" 0

(That's assuming that the name of the object is "Dovahkiin Sword")

I had a similar problem. Using the Help command worked with the tutorial weapon, but I still couldn't find the formID of the tutorial armor. What am I doing wrong?
