Thank you Tim,
Can I exclusively apply it to my own books instead of globly?

That message is probably relateing to the macro security settings you have
for Excel. Tools...options....security...macro security

Depending on what setting you have this set to it will deny all macros, or
ask if you want to trust the macros (medium) or open without asking. (This
one is not recommended unless you are 100% sure you can trust the source)

When I open a workbook with macros, a msgbox "if I want to enable the
Macros" appeared.
Is there a script for Auto_open() to enable by default.
Thanks
