"Tools->Macro->Security options"
needs to be set to Medium?
Mark I replied to your pm. Medium should work though you want excel to ask if you want to enable the macros for supertiller.
There is no tools
I had to add a "developer" to even see macro security.
Excel 2007 and newer are a lot different than the older versions. I had 2007 at work but 2003 at home. I haven't worked wit 07 for two years so I'm not much help.
