Hello All,
I am putting together a website to post all my Star Trek themed stories and hoping in the future to post other authors' stories as well, I wanted to add a rating system to each story or that's my plan.
I think I got all the stuff connected and whatnot but I this: Wix code SDK Warning: The numRatings parameter that is passed to the numRatings method cannot be set to null or undefined. I am lost as to what happened, I am decent at webpage stuff so I am lost. Please, can someone provide me with the answer to the question as to why I got this warning and how to correct the issue in easy steps. Please and thanks.

Please follow our guidelines when posting in this forum.
If you are following a review tutorial from Wix or third party, then please post the link.
Otherwise, please post up your code that you have used.
As for your error message, the numRatings parameter is not getting any number value so it has nothing to pass on in your code process.
