What rules should we use in combining the two rows? Which columns have Date
and times? Which columns do the results go in?

Greetings, I have two worksheets which are similar and each have date and
time column data headings in addition to other columns.

For every row which has a matching date and time in both worksheets, I would
like to combine the data for that row from both worksheets into another
worksheet.

For every row with a date and time in either worksheet that does not have a
match in the other, that row will be discarded.

Sound familiar to anyone? Thanks.
