Hide blank rows

Hi all,

Assume you have a range where column A is filled with the products and the rest of the range with some numeric values. The problem is that there are way too many blank rows. What the code should assume as "the blank row" is:

The whole row except column A
The "blank" cells in a row is an IF "" statement in fact.

Also I need a code to unhide hidden rows.

Any ideas?

Thanks a ton guys! See dummy...
