I have created a Vision Client Tag named as IncompleteTasks. Also, have used the `lookup()` function to set the background of the template based on the query. This suggestion was given to me in my previous post. Now after doing it, I was caught up with one error and warning as described below:

**Warning Scenario:**

> I created a Vision Client Tag and selected a table from the given source. Also have mentioned the datatype as the dataset. However, when I save the program, it gives me a warning stating: “ **Error Running Query** ”

**Error Scenario:**

> I have created a Template Parameter named Station which is a UDT. Now on the color property, I’ve applied expression using lookup() function as suggested above. Also, have used a property StationNumber from the UDT itself and got an error stating: “ **Can not assign orphaned UDT instance to a component property** ”

Can anyone suggest what should I do to resolve the issues?
