Datatable Lookup Return

[Jersey_Practical_Sho (Jersey Practical Shooter “X X Sonic Loss Xx”)]

So if a value is not found in a datatable lookup what is returned in the output variable?

I have an if statement and I thought the below would be correct but its not working
Client_Name is “null”

[indra]

@Jersey_Practical_Sho try this Client_Name=“”
