I have to apologize for my ignorance in advance. I know nothing of VB or
embedding macros in Excel. I can learn quickly though. Before I get to the
real question, does anyone have a suggestion for a website that can hold my
hand through the basics of using VB macros in Excel starting from the "I'm
an idiot" stage?

I want a macro that I can electively run on a single sheet that will hide
all rows based on a formula I define. I'd like it to operate based on a
button on the sheet or even just by entering the sheet. Either is fine. I
know this is actually two or three questions in one:
1) how to initiate the macro by entering the sheet or pressing a button
2) how to hide specific rows in a macro
3) how to use a formula in a macro (maybe not really an issue)

Thanks all.
Scott
