enable content disable?

You can go to File -> Options -> Trust Settings -> Macros and enable all content.

Personally, I'd go into the Trusted Documents tab of the same area of make that single document trusted, or a single location.

VBA is pretty powerful stuff, and bad code can exist even in this petty little code.
A nasty Excel file can wipe your hard drive without warning if everything is always enabled, in less than 100 characters of code.
