How Do I Find the Greatest Value in an Array?

Hmm, normally I wouldn't a question like this, since you haven't shown any effort. However, the script is simple:

I recommend writing a generic for loop that iterates through the table (goes through it), and compares all of the values to each other, returning the largest one. I'm not sure if there's a simple way, but this is my way: (I didn't test this since I'm not home, but it should work)

local My_Table = {1,7,4,30,5}

function FindGreatestValue()
    local greatest = 0
    for _,v in pairs(My_Table) do
        if (tonumber(v) > tonumber(greatest)) then -- Tonumber isn't needed, but in some cases it is
            greatest = tonumber(v)
        end
    end
    return greatest
end

print(FindGreatestValue()) -- Will print what it returns, which would be 30
