Attachmod not compiling

[bwins95]

I'm trying to make my elemental harpoons mod more convenient. I want to make it so the harpoon mods can be changed anywhere instead of only at a weapon bench. when I found the attachmod in the wiki I thought of using a terminal.

 

The problem is when I try to compile the script in the terminal it says AttachMod is not a function or does not exist

 

What am I doing wrong?

Weapon DLC03_HarpoonGun
ObjectMod DLC03_mod_HarpoonGun_Mag_Flaming

DLC03_HarpoonGun.AttachMod(DLC03_mod_HarpoonGun_Mag_Flaming)

Any idea?

I put the script into the script fragment section of a terminal entry, fill the properties and click compile and it says "AttachMod is not a function or does not exist"
