New Post: SP2010 – Updating multiple list items

Ok, this is what I have, but it's giving me an error:

var ReleaseDateMainNotFormatted = $("input[title='Actual Release Date']").val();

var ReleaseDateMain = $().SPServices.SPConvertDateToISO({
  dateToConvert: $(ReleaseDateMainNotFormatted).val()
});

The error it gives is: "Error: Syntax error, unrecognized expression: 6/16/2014"

So, it's getting the right date now, just not the right format? I'm guessing maybe after the .val(), in the parenthesis I need to format it to match the destination maybe? Desintation column is a DATE ONLY field.

Or am I way off?
