How to Get the Index of the List

List.IndexOf not giving desired Result

[Capture] Hi All, If you see my Script, I have 75220016 in both my list but List.IndexOf is not able to read it, I don’t know why. May be because it is a number ? Because once I add -1 in both of my list’s, it starts reading it. Is there a solution to it? Thanks.
