Error: attempt to index nil with 'FindFirstChild' How to fix this?

I have a game similar to ToH. The tower changing script sometimes does not work. The script works fine with no problems for some time, then randomly it stops working. I get an error message on line 146 saying: attempt to index nil with 'FindFirstChild' This is my script:

Maybe try getting the Character with this:

v.Character or v.Characteradded:Wait():FindFirstChild("Win")

I'm not very sure if this actually works, but it's always worth a try!

I tried it and it gave this error: Win is not a valid member of Model "Workspace".SpongebobRules26 SpongebobRules26 0 — 1mo

The error was on line 147: v.Character.Win:Destroy() SpongebobRules26 0 — 1mo
