Hi there,

SQL Server scalar user defined functions must be called using 2 part names. You will see this error if you attempt to call the functions using a 1 part name. Can you check if that is the problem ?

So if your function name is "function1" and is defined in the dbo schema, then instead of

"select function1()" you should call it as "select dbo.function1()"

so in your situation, you should use;

WHERE quantity>dbo.AverageQuantity('DVD')

good luck =)
