Hello Mister X
Try the attached. I edited the relationship between the two data sources so that the Dates match on Month/Day/Year of date (do this on Data...Edit Relationships).
Then I changed the date pill on the column shelf to MDY(Date) - and then you can add Event to the colour shelf.

Exactly that! Thanks Andy!! Just trying to understand, for date relationship, is the format there prevailing over what you set within the data source?
