Problems with Google Map – Single Marker Map

I'm having problems with the zoom level on a single marker map, no matter what value I enter it is still 100% zoomed in
this is the code I am entering, but no matter what value I put in the zoom level is the same.

jQuery( document ).ready(function($) {
$("#js-main-map-canvas").wpvmap({
generalMapZoom : 5
});
});
