Many thanks for your reply.
To explain more
With the current price's of fuel at the pumps, I have made a small website for local use to highlight high and low price's.
The database is updated by myself and other user's.
After a week, if the station is not updated, I delete the post.

I had an idea to color a post if it is 1 day old, so user's can see at a glance if the price is valid.
The price's can change daily. Last summer, the price's where changing more than once a day in some stations.
I know that other thread, and have tried to add a code to make this happen,
With my limited coding skills, though, it's not going well
