#6 Start calendar at month

[Anonymous]

I'm trying to show the datepicker starting from a month in the past; I'm guessing I need to use showCurrentAtPos but not sure how.

Here's my code:

var dates = jQuery('#course_dates').val();
var dates_array = dates.split(',');
var firstdate = new Date(dates_array[0]);

jQuery('.mdp').multiDatesPicker({
    dateFormat: "dd/mm/yy",
    altField: '#course_dates',
    numberOfMonths: [2,3],
    addDates: dates_array,
    showCurrentAtPos: firstdate.getMonth()
});

But this is not working... help/suggestions?

Thanks,

David
