I am trying to satisfy 2 criteria in order to change the color of a cell:
I hilighted cells b27:b56) and then went to conditional formatting and
entered this formula. I want the b column to turn blue if the adjacent cell
in the C column is greater than zero. I am spinning my wheels on this.
Thanks in advance for your help. You folks always come through for me!

=and(c17:c560,isblank(b17:b56))
