trying to set custom drops with percent chance

[Maddude174]

im a complete beginner and this is pretty comlex for me to figure out, so i resigned to finally asking for help.
my code right now (barebones to test) is compiling successfully, and does occasionally trigger a <null> dropped title, but doesnt actually drop anything.

for testing purposes, i only have drop set to small bag, but i want it to drop one of these (with a percentage chance per item)

again, the code *technically* functions; just not as required.

variables:
  {skull.line.name} = "%{_name}%"
  {skull.line.1} = "&eValue: &a${VALUE}"

variables:
    {skulldrop} = true
    {dropchance} = 100
    {smallbag} = "{SkullOwner:{Id:""e1c1a194-7e86-414f-86bb-42d82a21cfb8"",Properties:{textures:[{Value:""eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvYjVmNTIxZGQyMTVhOTU4NjIxYTAwZmMwOGRmYTU1NTIyZTEzODNlNTNmZGM3ODFhOTMxNzY2ZDQ2ZDAyYWMwNyJ9fX0=""}]}}}"

I'm so confused.
What are you trying to do ?

 

[Jakkeren]

Please elaborate your issue, and what you're trying to accomplish - we can't read your mind.

There's clearly a lot of issues and un-optimal things in your skript, but we won't be able to help you unless you actually tell us what you're trying to do.

 

[cuddlytrap]

i am confused but in the title it said something about chance so i would do like:

on death:
  if victim is zombie, or creeper, or skeleton, or husk:
    chance of 8%:
      set {_drop} to {_smallbag}
      set {_name} to "&6Small Bag of Gold"

again, please state what you are actually trying to do if this is now what you were trying to do
