I have had some fun getting some conditional logic working on this form here.
For the most part it is working well, excpet I can't see to find a "clear form" button incase you want to untick some options.
I also want a button to say "calculate" which seems to happen automatically, but adding a button would be fantastic if possible.
You can see the form is working well....just a few little tidy ups and I will be over the moon.
I hope to hear back from you soon.
