Excel 2007 : Relative reference conditional formatting

I am trying to make a conditional formatting formula that applies formatting based on whether the column A cell has a value.
Basically, if the conditional formatting is applied to cells G3:L3 and A3 is blank (or value is blank/0) then apply formatting.

I have attached an example (that doesn't work this way)

How can I change the formula to do this?

Select G3:L3 and go to Format > Conditional Formattin and select Formula Is from lefmost dropdown and try this formulae
