The AND function has a required syntax of AND(<logical1>, <logical2>).

How to do it...

1. Open the Chapter_9_DAX solution, select the CRASH_DATA_T table, and make sure you are in the data Grid view.

2. Scroll to the right until you find the Add Column. Then in the expression box, add the formula to determine the number of vehicles and number of fatalities involved and press Enter to create the calculation. You will then see a label added to each row:

           =IF( And ( [FATALITIES]>=1, [VEHICLES]=1), "Single Vehicle 
           Fatality", "Multiple Vehicle Fatality" ) 
   

3. On the Properties window, change the...
