Hi!

First you have to learn C-Script to understand the errors - so please try some simpler things first...

- the first error means that you somewhere in your code already defined an object/function with the name "crate".

- the second error depends on the other "crate"-object (it's readonly).

- the last error is a spelling-mistake - try "crate" not "create" - sorry - wrote the code without editor/test.
