I'm very new to marcos, so please be gentle....

I have a worksheet named Summary which uses Auto Filter (Non-Blanks). It's
important that none of the formulas get messed up on this page, so I've
protected it. Depending on data entered on other worksheets, rows on the
Summary sheet may or may not be blank. I would like Summary to re-do the auto
filter and remain protected everytime the workbook re-calculates. I tried
recording a marco and here's what I've got so far. All help is appreciated.
It says Active sheet, but Summary will hardly ever be the sheet I'm looking
at when the workbook calculates. I only need it to affect the worksheet
Summary.

Thanks,
