Question: Question moved as I was sending a reply

I don't know where my last exchange with @mz6687  has been moved (not to the initial question  https://www.mapleprimes.com/questions/237066-Determinant-The-System-Hangs for what I see).
Nevertheless here is the reply I was sending to @mz6687  which ended with the message "Page not found".
Are_you_ok_with_that.mw

Could the one who moved the question meanwhile be so kind as to attach this reply?
TIA
