αρχάριος ζητάει τα φώτα σας για την javascript

[Bafurious]

Γειά σας, είμαι αρχάριος και προσπαθώ να μάθω τα βασικά της javascript μέσω του codecademy. Λοιπόν για να την τα πολυλογώ εδώ είναι ο κώδικας όπου περιέχει if/else μέσα σε switch αλλά πάντα μου βγαζει το σφάλμα SyntaxError: missing ) after condition.

Έχω ελέγξει τις συνθήκες και λόγω της έλλειψης γνώσεων και υπομονής κυρίως ζητάω τα φώτα σας γιατι θα τρελαθώ

            if (yes_question === "RP" || yes_question === "PVE") {
                console.log(yes_question + " " + "is chilling and casual :P"); }

Ευχαριστώ πολύ, Μανώλης

EDIT:  χαχαχα τελικά είμαι για πολλές σφαλιάρες, μόλις εκανα επικόλληση τον κώδικα πήρε το μάτι μου ένα κενό στην μεταβλητή pvp_rating. Ήταν γραμμενη σαν "pvp _rating" αντί για "pvp_rating"....
