Hiding cells when the value of a cell is a certain number

I want to be able to hide a selection of cells, including the border formatting, when another cell has a particular value (in this case I want the cells visible only if the value in the cell is above 0). I've looked around and can't seem to find anything relevant. Anyone got any ideas?
Cheers.

Hi shockerty,

One approach is to select the cells you want hidden, remove all regular formatting, then change the font colour to white.

Now select "Format --> Conditional Formatting" (or whatever the path is for Excel 2007 to Conditional Formatting), and select Formula is: and use =$A$1>0 where A1 is the cell with your "particular value". Now set the conditional formatting to make the font colour automatic and the borders as you prefer. Click Okay.

Cheers,
