I have the Following Code in My stored Procedure. i have already declared that @vReturnVar but still showing 'Must Declare the scalar variable "@vReturnVar".

What line is your error coming from? Could the variable be out of scope at that point? -

Msg 137, Level 15, State 2, Line 19 Must declare the scalar variable "@vReturnVar". -

I am Just Trying to Run the main Select query to check the result. but the following error is shown. -

If you are just selecting and executing the SELECT query then it has no concept of the variable. The variable must be part of the SQL you are executing. Copy and paste that section into the beginning of your query that you are trying to run. -

You almost certainly want to look at JBrook's answer below too -

Shouldn't it include a "COUNT()"

        SET @vRCount =(SELECT COUNT(Distinct Shift) 
                       From [dbo].[tblMMDLogEntry] 
                       Where Shift Like 'Night     ' And Date=(SELECT  MAX(Date)  
                       FROM [dbo].[tblMMDLogEntry]))
