how to call scalar function in sql server 2008

Question

I have created a Scalar Functions, it was created successfully, but when I call the function using select statement, it says Invalid object name \'dbo.fun_functional_score\

Answer 1

For some reason I was not able to use my scalar function until I referenced it using brackets, like so:

select [dbo].[fun_functional_score]('01091400003')
