I have a dates in column J and also dates in column K

What I want to do is check each date in column J to make sure there are no
dates in column K that are within 6 days of it.

That is:
J2=01/04/2005
no date in column K can be <07/04/2005

If there are any then possibly create a list of C2 and the C column values
for the records within 6 days.

Hope this makes sense.

Thanks in advance.
