Excel Service option in Publis menu in Excel 2007

Hello,

I'm trying to get Excel 2007 workbook published over the network using
SharePoint 2007 Server. I found instructions (videos) on how to do it and it
is all fine till the moment I need to publish my workbook to the Excel
Service.

Video is showing that this option should be in Publish menu, but I don't see
it there in my installation of Excel 2007.

I would greatly appreciate it if somebody would let me know how to make this
option visible.

I can upload my workbook to the Trusted Excel Service Location, but I cannot
control visibility of sheets and visibility of ranges in sheets. For this I
need to set Excel Service Options which can only be found when you run Excel
Service from Excel 2007 (as I understand).

Thanks...
