Hi Kathi, having just watched week 2 i have a question on the variables. I have a scenario where i need to use my first drop-down to be selective of one of 2 sources of info. lets say Departure Date or Return date. These would be 2 different columns in a table as the source of the data, to dictate the rest of the data for that day only, depending on whether it was a departure or a return. The second drop-down would be a date selector to be fed into the first parameter. The date of the Departure or Return. How could these 2 parameters be linked, when the source of the first is changing.
