What am I doing wrong?

can you put your full script or a little more? line 19 is blank from what you sent BulletproofVast 1033 — 4y

try printing RoleList right before line 19, see what is inside of it. Benbebop 1049 — 4y

maybe the table is supposed to be something like local Rolelist = {'Mafia', 'Doctor', 'Jailor'} (without the = Number) BulletproofVast 1033 — 4y

After testing it, for some reason its counting Rolelist as having zero entries. Maybe cause its a dictionary and not an array, but I don't remember that sort of behaviour being a thing. Benbebop 1049 — 4y

I don't believe you've provided the full script; so I don't know where the line 19 quoted in the title is.

I hope maybe by rewriting this section I can help others understand this more.

01local RoleUsed = {}
02local RoleList = {}
03 
04RoleList["Mafia"] = 1
05RoleList["Doctor"] = 2
06RoleList["Jailer"] = 3
07 
08local IntValue = Instance.new("IntValue")
09IntValue.Name = "Role"
10IntValue.Value = 0
11IntValue.Parent = plr
12 
13local function random2()
14    local n = math.random(1, #RoleList)
15    repeat
16        n = math.random(1, #RoleList)
17    until not RoleUsed[n]
18    RoleUsed[n] = true
19    IntValue.Value = n
20end

This is the full script

11    local Id = Instance.new("IntValue", plr)
12    Id.Name = "Id"
13    Id.Value = 0
