The only error in the console is this:
http://www.brandmagik.com/rob/wp-content/plugins/acf-repeater/js/input.js?ver=1.1.1 Failed to load resource: the server responded with a status of 404 (Not Found)
Checked the plugin files and js folder was empty for some reason. reloaded all the files from the zip and it works now.
Thanks for pointing me in the right direction.
