Broken update page
Not sure what I've broken here - I had a bit of trouble getting my dynamic dropdowns to work. They are now, and populating with the correct values on the update page. But the update isn't working. I'm sure it must be something simple, but I can't see it for looking as I've been working on this for a while.
I have attached the page below - if someone could have a look that would be much appreciated. Hopefully a simple one!
