First off, apologies if this is in the wrong place and let me know and I'll move it. I've been trying to look through the FAQ, the New To Modding Tutorial and a few other web guides and I'm just not making the connection here to what I am doing wrong. What I want to do is really simple, and I am sure there are a thousand topics on it already, but the searching today is giving me a headache. Simply put, I want to change the damage values of weapons in The Pitt and other DLC. Another mod that I am using makes these weapons about as useful as throwing a crumpled piece of paper at a super mutant behemoth. I've been using FOMM and TESSnip to change the values, and as far as i've gathered i take out the GRUP(WEPS) and copy it to my mod, edit the values for the damage, save, go up to the TES4 tab, click the drop down from the file/edit/etc and click add new subrecord and if i am thinking correctly i change it from NEW_ to MAST and click the right hand side of the textbox and type in ThePitt.esm or Fallout3.esm so i set a master file for my "mod" to work from. However, the problem is arising that when i do this it gives me an error and says cannot save (something about invalid data relating to the file) Being pointed to the right area of a thread would be great and get me going, I'm not honestly expecting anyone to hold my hand and walk me through it step by step (unless someone did have the time to do that) but a quick and dirty tutorial on it better then the thread i found on No Mutants Allowed would be great.
