You just want to hide the other 2 sheets?
The manual approach is to select the 2 sheets (by holding CTRL or Shift) then go use your Format Menu-Sheets-Hide.
Of course if the ppl you send this to also know excel they could easily go to formatsheetsunhide unless you use some passworded sheet protection.
Hope that helps somewhat, -please reply if you were actually shooting for something more complex though.
