I need conditional formatting for rental increases that are 1) highlight the date for notices that are less than 30 days away and 2) once the notice is sent, to remove the highlight (See the attached image). These need to apply to the entire column. I have a conditional formatting for column C that anything that is 45 days from today's day will be highlighted in red; =TODAY()+45. In column F, the property manger will input a date of when she sent the notice. Once a date is entered in to the corresponding cell, I'd like the red highlight to go away. For example, if she sent a notice to Ringo on 2/1/2023, that date would be entered in F4. That will remove the red highlight in C4..
