Excel for MAC using chart templets

[Raleigh1934]

I am retired and reasonably familiar with Excel, but not an expert. I am having no luck in using self developed templets. I have read all the "Help" menu instructions with my excel version:

Excel for MAC, ver. 16.43, 365 subscription.

I could use some help?

@Raleigh1934 On a Mac myself. What's the problem? Difficult to diagnose "having no luck in using".
