Looking at VBA Help for the Sub statement, the "name" argument "follows
standard variable naming conventions".

Looking at VBA Help for variable definition:

Variable names must begin with an alphabetic character, must be unique
within the same scope, can't be longer than 255 characters, and can't
contain an embedded period or type-declaration character.

Type declaration characters include $ (string), # (double), % (Integer),
& (long).

Brackets delimit argument lists, so are not valid within names.

Since spaces delimit VBA tokens, a name can't contain a space character,
either.

This will work:

Chart_1A_MS

I'm having trouble finding what's excluded from use. Is there no list of
forbidden characters? I wanted the macro names to correspond to that of the
charts. Example "1A) MS" ... without the quotes. When that was rejected, I
assumed the bracket was the issue and rewrote to this: "1A_MS". No luck
either. So I assumed numerics as first charter were forbidden and chose:
"Chart 1A_MS". Rejected!

Help please.
