James,

By default STR function returns a string 10 character long but you need 4 to match hbstb and tent. You have to specify 4 as the second parameter for the STR function as shown below

select iif(hbstb<>" ",hbstb,iif(tent<>" ",tent,str(iif(barn>0,barn,0),4))) as stable from stnhorse order by hip_no
