Hey why do I get an error when I want to define values?
I'm just learning the program 😞

Any help appreciated!

My guess is that you used the vector/matrix index instead of the literal/subscript index.

Use the index you get by pressing "Ctrl -"

Could you share your whole worksheet file?

I manage the Creo and PTC Mathcad YouTube channels for PTC, as well as all PTC Mathcad marketing in general.
