Selenium Web Driver: NoSuchElementError

Salutations!

I'm building a web scraper using Selenium Web Driver and Excel VBA. For a specific website, I'm unable to find elements on the webpage, though I'm able to login to the website using the web driver.

Here's the website in question:

 WebsiteURL = "http://ift.tt/2huYIN6"

Here's the code in question:

 driver.FindElementByXPath("//*[@id='payerDropDown_chzn']").Click

I've tried using byname, byname & byclass but none of the methods are able to find the element. I also tested this on multiple elements on the page and it won't work.

If you have any advice on how to find the elements, please let me know.
