'Must declare the scalar variable' in FETCH

[jeanid]

I'm new in StackExchange, working with Microsoft SQL Server (also new). I'm trying to recover data from a table using a cursor. I've declared all temporary fields but I'm getting an error when I do the FETCH NEXT. The code is:

CREATE TABLE #RedsRisk (
    PolicyCode int,
    LocationCode int,
    OriginalCurrency varchar(10),
    BusinessUnitCode varchar(30)
);

--I feed correctly the table in the process, then

DECLARE @PolicyCode AS int, 
        @LocationCode AS int, 
        @OriginalCurrency AS varchar(10), 
        @BusinessUnitCode AS varchar(30);
DECLARE RRisk CURSOR FOR

SELECT

PolicyCode,

LocationCode,

OriginalCurrency,

BusinessUnitCode

FROM #RedsRisk;
OPEN RRisk;
FETCH NEXT FROM RRisk INTO

@PolicyCode,

@LocationCode,

@OriginalCurrency,

@BusinessUnitCode;

And then I have the error:

Msg 137. Must declare the scalar variable "@PolicyCode".

What's wrong here?

Thanks.

I can recreate the described error but only when highlighting the FETCH NEXT FROM Part and executing that (like @J.D. commented).

When completing the example with CLOSE RRisk, DEALLOCATE RRisk and DROP TABLE #RedsRisk and not selecting any code the code runs multiple times without error.
