Hello from Steved

In Column D1:D1000 I put in Kilometres
What had happened a figure 124,957 was A mistake

I would like to know please if the below is possble Thankyou.

In Column D1:D1000 if the figure is a minus or greater than 5,000
I need to know, I am thinking that in Cell M1 if the above occurs then true
if not it will read normally False, also in D1:D1000 can the cell be
highlighted
maybe the cell background be Blue if not then in Cell M2, M3 and so on to
inform me where the mistakes are. if the above is not possible would you
give me some sugguestions please.

Thankyou for your time on my issue.
