How to compare a number value to an index value in your table?

Problem:

First of all you should not use "table" as a variable seeing as it is a keyword and most likely will cause errors so I went ahead and called it table2 . Second you don't need a variable that you have named as word to hold an empty string.

Solution:

Indexing is your friend. Indexing basically just means to take or add a value to a table. Since you want to correlate your variable to your table you simply index your table with your variable. Which will make more sense when I show it.

Code:

local Button = script.Parent:WaitForChild("ClickDetector") --I added this to reference to the ClickDetector, assuming you were referencing to that
local table2 = {"One","Two","Three","Four","Five"} --Changed the name of the variable
local value = 0

Now we move to the event that you can change depending on if it was a gui or to keep it if it was a ClickDetector

Button.MouseClick:connect(function()
value = value + 1
end)

Next we move on to the for loop that you did to allow you the capability to index for this particular case

for i,v in pairs(table2) do
	local word = table2[value] --This would be indexing
    print(word) --I renamed the variable to be referenced to this instead of a string
end

All together we have

local Button = script.Parent:WaitForChild("ClickDetector")
local table2 = {"One","Two","Three","Four","Five"}
local value = 0
Button.MouseClick:connect(function()
value = value + 1
for i,v in pairs(table2) do
	local word = table2[value]
    print(word)
end
end)

If you have any problems or any questions don't be hesitant to ask. I would be glad to answer. If this helped you don't forget to accept the answer! Also note that I am referencing to the event of a ClickDetector. Change the event if needed. Also note that after it goes passed "Five" in the table it will print "nil".
