>>>Hi,
>>>
>>>I need to create a variable in a report that will count the number of distinct values. For example, if the report has a column EMPLOYEE_ID the variable should count how many employees are in the report. How? I tried to enter in the value to store "DISTINCT( EMPLOYEE_ID )" but it gives me error. TIA for any help.

>>Initial value: {some value that can't occur in the data}

>>Calculate: None

The reason I made this variable private is so that it would be in the scope of the report. And the code for the sql select is as following:

Actually, you don't need the variable to be private if it's declared local in the same routine that runs the report. Reports can see locals from the calling routine.
