Highlight Row of Checkboxes if NONE are Checked

Question

In my spreadsheet, I would like to highlight a series of cells (all in the same row) between two columns when all of the boxes are not checked.

For example, in the sheet below, I would like to highlight D4:I4 because none of the boxes are checked.

Thanks in advance!

Answer 1

Add formula to conditional formatting:

=not(or($D1:$I1))

and apply to D:I range
