$30 - $250

Project Description:
I am looking for some one to fix some issues I am having with my website that were working before. First of all the drop down arrow on the links along the top of the page do not appear sometimes depending on what page you are on and what browser you are using. Also on product pages when you hover over the second image it is supposed to pop up in the large full image space and chrome it does not change in the collection pages either.
