I am trying to find a formula that would help me find how many cars overlap and are in the lot at the same time but only when column D is False. I would then want to count how many cars are in the lot at the same time. The start times are located in B2:B7 and end times are in C2:C7. I've tried using a SUMPRODUCT function but was wondering if there was an easier way to go about this and include the function to count the number of cars that overlap.

Is there a way to write ino the formula for it to be able to distingush the change in coloum A? Meaning the formula would only check overlap times when coloum A is the same? Thanks.

Waterfall charts in Excel?
Office 365 customers have access to Waterfall charts since late 2016. They were added to Excel 2019.

There repeating values as you can see in the table I posted, the repeating values just shows that they are in the same lot. Which means there are 336 different locations...Thanks for your help.

I'm not sure how you want the results. The formula below indicates the number of overlaps for each row.

This does help for the most part, However when it runs into a row where the D colomn is TRUE it returns a negative number instead of disregarding it's data.

Could you show an example where this occurs?
