Hi Anji,

You have a spell mistake in your controller code.

Please try to paste as below and check: 
({
    test: function(component, event, helper) {
        var a=component.get("v.aval");
        var b=component.get("v.bval");
        var cval=a+b;
        component.set("v.cval",cval);
        
        
    }
})
Hope above information helps. Please mark as Best Answer so that it can help others in future.

Hi Anji,

Please find the solution.

test: function(c,e,h){
                var a=c.get("v.aval");
                var b=c.get("v.bval");
        var cval=a+b;
             console.log("outside if:::"+cval);
        if(cval){
            console.log("Inside if:::"+cval);
           c.set("v.cval",cval);

        }


     }

Actually, In your code, there is no data inside this variable "cval" so how you can set if there is no data.

c.set("v.cval",cval);

I have correct your code if there is no data then it will not enter inside the if statement.
Please let me know it is working or not.
Please mark it as the Best Answer if it helps you.
Thank You
