Is there a way to run a macro that hides/unhides multiple worksheets based on
the value selected on a data validation list? If so, what would the VB
syntax be for the macro?

For example, if Cell A1 contains a data validation list with 3 values to
choose from (Account Info, Order Info, Billing Info) and Account Info is
chosen, I want to unhide the Account Info worksheet and hide the Order Info
and Billing Info worksheets. If Order Info is chosen, I want to unhide the
Order Info worksheet, and hide the Account Info and Billing Info worksheets,
etc.
