So I am currently trying to make a script that checks if there is more of one thing in the table. For example:
t = {"Orange", "Purple", "Grey", "Purple"}
The table would know that there is 2 of Purple and 1 of Orange and Grey.

Is there a way for tables to check if there is more of one thing in it?

I would do this:
local function getNum(array, value)
local num = 0
for i = 1, #array do
if array[i] == value then
num = num + 1
end
end
return num
end
t = {"Orange", "Purple", "Grey", "Purple"}
print(getNum(t, "Purple"))
The function takes an array, and a specified value.
Set up a variable to keep track of the number of occurrences of the value. Iterate through the array, and for each time we stumble across an element that matches the value we're looking for, add 1 to the variable we set up before iterating through the array. After the loop finishes, return the variable.
add this to your code:
if #t > 0 then
print("More things are in this table")
end

They're asking for a way of determining if an element shows up more than once in a table, not if the table has multiple elements.
Oh then you need to sort
