Select the Class module in Project Explorer (top left panel), in the
Properties window (typically bottom left panel but press F4 if necessary)
you should see
(Name) Class1

select "Class1" and rename to "clsChtEvents"

If for some reason you can't do that, replace clsChtEvents with "Class1" in
the normal module (I think in two places), and assuming the class you
inserted is named Class1.

Suggest head the modules "Option Explicit", which I see I forgot to include
in the post.

Sounds like this will be your first time to work with a class module (in
this case a "withevents class". Keep in mind the module is "instanced" with
the line
Set mcChart = New clsChtEvents

the class remains "alive" and responsive until the object reference
"mcChart" is destroyed, eg
Set mcChart = Nothing
note editing code can also destroy the object ref, you can run the SetChart
proc again if/when that ref' goes out of scope.

inserted a new Class "Class1" and tried to rename it to
"clsChtEvents" to no avail.
Obviously the sub SetChart() won't run.
Please pardon my ignorance!
