I have the following for a conditional formatting statement for a row

Formula Is =AND(ISBLANK)$L7),(TODAY()$J7))

in order to highlight the row yellow when the Date Closed cell (L7) for the
item is blank and the Closure Due Date (J7) has passed.

The row is highlighting when it is completely blank, with no data filled in.
I have only the headers typed in the appropriate columns, and am using the
format painter to format all my rows, and they are all highlighting yellow...

I have two other conditions set up with two other colors. The one giving me
the issue is Condition 2.

Condition 1:
Formula Is =$L7<""
So that the row highlights grey once the item has a Date Closed entered.

Condition 3:
Formula Is =OR($F7(TODAY()+730),ISBLANK($F7))
So that the row highlights orange if the last time the item has been
serviced was more than two years ago or there is no record of when it was
last serviced (F7 being the date of last service).

Any idea why Condition 2 is coming up True, and highlighting yellow, when
the row is completely blank and there is no information to determine if the
condition is True or False?

Thanks,
Deanna
