Hi durga, Can you please pass the name value pairs for the courseID and the empID and also please define the values as rule input or the local variables.

Whay you have passed in the brackets are either keywords or the values. If they are values, then please use local! or ri! or any valid domain to which these variables belong.

And if they are keywords, then pass the values to it. Adding the right syntax below.

rule!yourRule(value1: local!name, value2: local!age)
