I have three columns in my calendar on SharePoint 2013. They are:
- Truck Number
- Trailer Number
- Service Type
I am currently using a calculated formula column that states; =[Truck Number]&" "&[Service Type]
so now on my calendar when someone selects from drop down of Truck and service it comes up on the calendar. How do I add into this formula the Trailer number if the user happens to select it? Thanks all!
