Hi, Before the OVER clause you have to set an analytic function. For example when I want to use the AVG function with an OVER clause, I usually follow this pattern: ``` AVG ( <expression> ) OVER ( [ <window order by clause> ] ):number ``` This example will return a number and it can be extrapolated to other analytic functions. For more information, check the section[ Analytic Functions (Window Functions)]( of the Virtual DataPort VQL Guide. Hope this helps!
