Did you set Test #3 as an Input property or an Output property? I believe it has to be set as an Output property and this could be causing your error.

You are getting this error because you used an input property to calculate something based on other input properties. This creates a circular reference.

If you simply want to display Test1 + Test 2 within your component then do not create a property to calculate it. Simply put Test1 + Test2 in the Text property of a label. Then it will display the value.

Then if you want to output the result of Test1 + Test2 create and output property called Test3 and put the code Value(Label3.Text) inside of it. Now you can access the result by referencing the component like this: ComponentName.Test3
