I just realised the '+' disappeared in the post but does exist in the file.
I will write a '+' juste after the ':' at the end of this line to check: : + 1

I finally tried deleting the Medical Lab part.
It will then go further up to the Ultra-recycler facility and then the same error again, I guess in the following:

I think I got it. My computer has is expecting ',' as decimal separator instead of '.' and then when your program meets a decimal number in formula it will not process correctly.

But I'm not sure if you could force the decimal separator in your code to be '.' instead of windows default one ?
