Not sure about the function you made, I'm not good with scripting yet. I do know that the line load_wepon_specs_from_table, Istanbul referring to your wepons.csv. (a table with all weapons info (ie. weapon name, cost, in the box or not, is a wounder weapon, spawn a wallbuy,ect....)) it is located in share/raw/gamedata/weapons/zm/zm_levelcommon_weapons.csv, and that is were you should, theoretically, be able to delete weapons from map, change wallbuy cost, and add or remove from the box. However so you don't effect all maps or mess with the original, you should copy it and paste it in a folder in user maps like: usemaps/gamedata/weapons/zm/zm_levelcommon_weapons.csv. and from there you can edit the csv file and only effect the map you are working on. also you need stringtable::gamedata/weapons/zm/zm_levelcommon_weapons.csv line added at the bottom of your map's zone file. That is what all the tutorials say but it hasn't worked for me yet. Good Luck 

Following all the tutorials on line to change wallbuy weapons. My wallbuys are from craftedanimation preb. so I've Made a custom weapon.csv and the folders needed. added the stringtable:: line in my .zone file and made sure the give_wepon function() in my mapename.GSC and csc file were set to my weapons.CSV file and nothing works values will not change and my bo4 weapon ports work with console and are in the box but have a 0 cost and won't give them to me. No one has even offered any help or suggestions, so please I just want my custom bo4 wallbuys to work and change the cost of my wallbuys so they are not at 5000 for an A.R.

Did you ever solve this problem, I have the exact same issue. Edit .csv and nothing happens it ignores all changes.

I am just now getting into custom zombie map making and barely know what I'm doing catching on very quickly because of your guys tutorials and how and I think it's skylord here with all of these downloads I just want to thank you so much man I did not want to spend the time ripping all these weapons and other ones this is so awesome thank you so much really appreciate it keep up the great work also do you know how I could get things like the staffs or wrath of the ancient and upgraded bows things of that nature
