I have a Directory on my website built here: https://www.doctology.com.au/directory
There are buttons at the top that when clicked only bring up options that are relevant to that button, however, when I click the buttons they do not link anywhere and just bring up a blank page eg. when I click "Practice Management Software" it should bring up any listing with "PMS" attached to it (see below).
When I click the "ALL" button on the site, all the options in the directory listing appear again. I have not personally changed any code.
Can anyone help?
