This is very impressive."; 4. replace an image in an existing page and fix the scroll bar which is not working properly; 5. fix the scroll bar to work properly in another 4 pages; 6. unhide a function which was hidden from the public view. note: cross browser compatibility testing is expected for both mac/pc (eg. ie6+, firefox 3+, safari 3+ etc).

Timeline: 5 days upon award; Budget: $350 + $150 bonus if you can start on Friday and deliver the work within 5 calendar days.
