Boolean Blank if cell is blank?

Geard Ledet

I am trying to create a boolean formula in which if the cell is blank the formula does not apply.... below is the formula I currently have

=IF([Av3000 Due Date]@row <= TODAY(), "Red", IF([Sure Seal Due Date]@row <= TODAY(), "Red", IF([Half Face Due Date]@row <= TODAY(), "Red", IF([Weld O Vista Due Date]@row <= TODAY(), "Red", IF([Av3000 Due Date]@row <= TODAY(+30), "Yellow", IF([Sure Seal Due Date]@row <= TODAY(+30), "Yellow", IF([Half Face Due Date]@row <= TODAY(+30), "Yellow", IF([Weld O Vista Due Date]@row <= TODAY(+30), "Yellow", "Green"))))))))

The issue I'm having though with the above formula is that if there is nothing in the cell its turning my Boolean red.... Please Help!!!

=IF(ISBLANK([Av3000 Due Date]@row), "Green", IF(ISBLANK([Sure Seal Due Date]@row), "Green", IF(ISBLANK([Half Face Due Date]@row), "Green", IF(ISBLANK([Weld O Vista Due Date]@row), "Green", IF([Av3000 Due Date]@row <= TODAY(), "Red", IF([Sure Seal Due Date]@row <= TODAY(), "Red", IF([Half Face Due Date]@row <= TODAY(), "Red", IF([Weld O Vista Due Date]@row <= TODAY(), "Red", IF([Av3000 Due Date]@row <= TODAY(+30), "Yellow", IF([Sure Seal Due Date]@row <= TODAY(+30), "Yellow", IF([Half Face Due Date]@row <= TODAY(+30), "Yellow", IF([Weld O Vista Due Date]@row <= TODAY(+30), "Yellow", "Green"))))))))))))

IT was all in the ISBLANK function!! I figured it out!!
