[SOLVED] Getting the OUT of a MySQL stored procedure?

Hi, I’m trying to get the value of a OUT variable from a stored procedure with no luck.
I’m using the code from the docs: http://doc.qt.nokia.com/4.7/qsqlquery.html#approaches-to-binding-values

I’m new to SPs so this is my test one:

PROCEDURE `abc`(IN x INT, OUT y INT)
BEGIN SET y = 11;
END

The code is:

I get this error: OUT or INOUT argument 2 for routine blah.abc is not a variable or NEW pseudo-variable in BEFORE trigger QMYSQL3

Thanks for any advice!
