VBA 4th conditional format in Excel 2003

I have a question that I have posted at OZGRID as well: http://www.ozgrid.com/forum/showthread.php?t=181780

about using VBA to kind of create a 4th conditional format.

For all the cells in my grid AQ3:BB66, they have three conditions.

2 conditions need to remain, but I would like to free one up for something else.

The condition I want to free up is:

If cell is not equal to ="" turns the cell green.

Is there any way I can apply this condition to this grid, through VBA?
