Not sure how to go about pulling the first line of the Array and then searching for other matches to see if the Start date -2days of line 2 is the enddate of line 1. If it matches then add total time and update my enddate on the OUT.

Hope this is helpful!

Wow! thanks for the post... I wasn't expecting someone to write the whole code for me :).

It is going to take me a bit to work through this but I think this will get exactly what I need.

I will post my final codes once I get it all worked out. Thanks again! Ray
