Lets say for example I have a frame and in that frame is a bunch of ImageButtons and in those ImageButtons are a bunch of Values and if those values were different like 1,2,3,4,5,6 how would i create a loop to find 1,2 or 3,4 or 5,6? (In the scrolling frame, there are buttons and in those buttons are values like 1,2,3,4,5)

Any Help? This is the script i created:

(NewCounter is the incrementing value)

01repeat wait()
02for _, v in pairs(script.Parent.Parent.Parent.ScrollingFrame:GetChildren(firstValue, secondValue)) do
03    if v:FindFirstChild("NewCounter") then
04        print("Passed 1")
05         NewCounter = v:FindFirstChild("NewCounter")
06         OtherCounter = v:FindFirstChild("NewCounter")
07        if NewCounter.Value == firstValue then
08            print("Passed 2")
09            firstValue = firstValue + 1
10            secondValue =secondValue + 1
11            print(OtherCounter.Value)
12            if OtherCounter.Value == secondValue then
13                print("Passed 3")
14                NewCounter.Value = OtherCounter.Value
15                NewCounter.Parent.Position = OtherCounter.Parent.Position
16                print("Weird script...")
17            end
18        end
19    end
20end
21until OtherCounter.Value == secondValue

It's a bit ambiguous what you want, but here's a few options:

01local sf = script.Parent.Parent.Parent.ScrollingFrame
02--Get children from firstValue to secondValue
03local newCounter
04local imageButtons = {}
05for _, v in ipairs(sf:GetChildren()) do
06    newCounter = v:FindFirstChild("NewCounter")
07    if newCounter and newCounter.Value >= firstValue and newCounter.Value <= secondValue then
08        table.insert(imageButtons, v)
09    end
10end
11--If you have named each ImageButton in a formulaic way, ex "Image1", "Image2", etc, you can just do this:
12local imageButtons = {}
13for i = firstValue, secondValue do
14    table.insert(imageButtons, sf["Image" .. i]) -- assumes that the ImageButton will always exist
15end
16--If secondValue is always 1 greater than firstValue and you have "Image1", "Image2", etc:
17local firstImage = sf["Image" .. firstValue]
18local secondImage = sf["Image" .. secondValue]
19 
20--Say you don't have them named in any special way and you want to iterate over all pairs (ex 1,2 followed by 3,4 etc) so that you can apply your Position command:
21--First, get all the image buttons into a dictionary/array where the key is newCounter.Value and the value is the image button
22local imageButtons = {}
23local ch = sf:GetChildren()
24local newCounter
25local max = 0 -- if you can guarantee that there won't be holes (ex you'll never have "1, 2, 5, 6" without a 3 or 4 anywhere), you don't need max and you can just use #imageButtons instead
26for i = 1, #ch do
27    newCounter = ch[i]:FindFirstChild("NewCounter")
28    if newCounter then
29        imageButtons[newCounter.Value] = ch[i]
30        if newCounter.Value > max then
31            max = newCounter.Value
32        end
33    end
34end
35--Now you can iterate over them easily:
36for i = 1, max, 2 do
37    imageButtons[i].Position = imageButtons[i + 1].Position
38end
