Complex Conditional Formatting

Hi all,

I am looking for some help with a more complex conditional formatting problem. I have a data set arranged by name (rows) and date (column). I also have a seperate table which list events that have occurred to each person on a particular date. I am trying to work out how to create a conditional formatting rule which highlights these dates on the data set. I have attached an excel file with an example of what i'm after.

Thanks in advance!

Sorry for off-topic interjection:

Although there is no official rule regarding this behavior, we request that wherever possible both the question AND the answer be provided in substantive detail here within the thread. An attached workbook is an excellent aid for posing a question and offering a solution, but solely doing that with no in thread explanation makes it difficult for researchers to understand or consider the Q & A of this thread without downloading what may be a pointless doc to them, if they can do that at all. Doing that also hides the content from search engines so others may never benefit from this.

I'm sure you understand, and we look forward to seeing you post your formulas/macros in your posts for the searching benefit of all.

Thanks again for all your hard work here!
