slidedown and slideup jquery

Question

I'm implementing the slidedown and slideup using jquery on mouseover and mouseout of the div:

$("#ReportViewerA").mouseover(function() { $("#ReportViewerA").css("background-color", "ANTIQUEWHITE"); $('#ReportViewerAtool').slideDown('slow');

        });
        $('#ReportViewerA').mouseout(function() {
            $("#ReportViewerA").css("background-color", "white");
            $('#ReportViewerAtool').slideUp('slow');

        });

Now. the problem is when the mouseover, the "ReportViewerAtool" div plays up & down, and the same when the mouseout as well. can anyone please suggest?
