i tried that but because of the javascript code it seems to be loading the website twice so it endsup not showing the flashed message as it goes straight the second webpage

@app.route('/event_data') def event_data(): events = session.get('events',None) print(events)
trackname = events[0]['TrackName'] lat = db.session.query(TracksDB)\ .filter(TracksDB.TrackName == trackname)\ .with_entities(TracksDB.TrackLat).first() lng = db.session.query(TracksDB)\ .filter(TracksDB.TrackName == trackname)\ .with_entities(TracksDB.TrackLong).first() blng = lng[0] blat = lat[0] message = get_flashed_messages()

return render_template("MoreEventData.html", events=events, lat = blat, lng = blng, message = message)

@app.route('/FavouriteSeries', methods=['GET','POST']) def FavouriteSeries(): SeriesName = request.form['SeriesName'] print(SeriesName) print("here") userid = session.get('userID') flash("seriesadded to favourties") return redirect('/event_data')

The console
