[SOLVED] Attempt to index number with number?

Im trying to make it check if the button that is clicked has a value with a name that is equal to the current number.

But for some reason it gives out the error on the title.

Heres the part where it doesnt seem to work:

if button:FindFirstChildOfClass("NumberValue").Name == currentbutton[correctbuttonsclicked]
then
    print("correct number!")
    correctbuttonsclicked += 1
end
