A problem with Tables positions

[SeichoSuru (Seicho)]

My English is not very good so I apologize in advance.
I’m trying to save CFrames with numbers

“i” is a position of a instance

but i can’t find any CFrame with SaveFrame[instance][i]

But when i try to do this:

here works.

Why does this happen?
I don’t understand

I believe it’s because T/WeitTime gives a result with a little inaccuracy. You could try rounding it with math.round.

saveFrame[i][math.round(T/WeitTime)] = part.CFrame
