Deleting Rows based on their value

Hi,
I am having trouble with the .SpecialCells(xlCellTypeBlanks)
What I need to do is for a macro to first go through a range ("G8:G50"), Add a 0 value to any blank cell.
Then I want the macro to delete the entire row for any of the cells that have a value of 0 in that range of "G8:G50"
