Script removing a string in a table. Expects a number??

There's a table with strings in it. For every time the script runs through one string of PurchasedEmotes, it will check if there are any duplicate purchases. The problem lies in Line 12, table.remove(PurchasedEmotes,PurchasedEmotes[i]) where the script says bad argument #2 (number expected, got string) when the whole table is strings only. And I have listed which number of PurchasedEmotes to get rid of, being [i] Can someone help me out?

for i = 1,#PurchasedEmotes do
    print(PurchasedEmotes[i])
    
    if #FindDupesTable == 0 then
        table.insert(FindDupesTable,PurchasedEmotes[i])
        print("first one")
    end
    
    for n = 1,#FindDupesTable do
        if PurchasedEmotes[i] == FindDupesTable[n] then
            table.remove(PurchasedEmotes,PurchasedEmotes[i])--???
            print("found a duplicate.")
            
        else
            table.insert(FindDupesTable,PurchasedEmotes[i])
            print("not a dupe")
        end 
    end
end
