[AccessD] Change to a Different Excel WorkSheet via Access VBACode

Charlotte,

Thanks for your insights into Access Links.

I do not have the experience with Access that you and the others here on AccessD have.

When I first started working with Access, I believe that I read something about the dangers of deleting and re-adding tables.  I can't remember the details but I have been a bit concerned about this approach.

Maybe there is nothing to worry about when doing this.

Thanks again,
Brad

Access isn't that flexible.  Links are kind of a special situation where
you have to replace a link, you can't just edit it.
