Hi @Alexander_Ward ,
try like below. just sharing suggestion. but as mentioned by other members we could easily implement this with if conditions. thanks.
use the following expression if((dt.rows.count>1),“greaterthanone”,if((dt.rows.count=0),“equaltozero”,if((dt.rows.count=1),“equaltoone”,if((dt.rows.count<1),“otherscenario”,“Default”))))
in the above expression greaterthaanone, equaltozero and equaltoone are the cases. inside of the cases we can built our validation logics.
type argument property in the switch case set to string.
Regards,
Kirankumar.
