I wonder if someone can help, im struggling to to get the jquery UI slider to work as i want it to.

i have a website setup with a jquery slider ( http://www.isaac-clayton.com/#work_section) its quite obvious what the problem is but i cannot for the life of me figure out why its not working.

the handle wont slide to the right fully. there are 14 images that it should scroll through and im wanting to add more as more clients are added to the site..

please could someone look at my site and see if there is something really simple that needs changing.

if you need any code etc let me know.

thanks in advance!
