Does anyone know why this building script to place pieces and build results in errors?

It results in an error with position, repeated no matter what and the second error if I rotated it before hand.

Errors at Line 85 and 93. 85: Attempt to index nil with position 93: Model:SetPrimaryCFrame() failed because no PrimaryPart has been set, or the PrimaryPart no longer exists. Please set Model.PrimaryPart before using this.

The errors only happen after it runs once. It's like it needs to update and realize that stuff doesn't exist. I don't really know.

Also there is another script, but it works fine.

I know this is a really long script and I'm sorry I just didn't know where else to look. If you read this all and find an answer then I really don't know how to thank you.

Does anyone know why this building script to place pieces and build results in errors?
