You cannot test a range for 0 or ISBLANK.

Must be done one cell at a time.

Select B17:B56 then enter this formula in CFFormula is:

=AND($C170,ISBLANK($B17))

Note the $ signs to lock the column but not the row.

Thanks in advance for your help. You folks always come through for me!

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