Thank you so much for your reply - I deleted everything I added, and downloaded and installed the plugin - but still no joy.
Here is a link to my form : http://dewetvanrensburg.me/sites/expert/central-kalahari/
I only tested in Chrome and Firefox, but the datepicker is not working, and I also can't enter any text to the newly added text field.
Again, any help and/or suggestion would be appreciated.
