Dear Yaw,
Thanks for the lift. I got it resolved. The device had a list of trusted certs so I had to request the root certificates from the server domain name owner. When I installed this, everything was resolved.
I would like to know how to resolve a this.
I wish to know if for instance someone selects option 4 in question 4, it should take him directly to XII (Pediatric Unit) but what I have now is to be able to select option 3 in questions (4, 12, 5 & 9) for pediatric option to open.
Since Cataract & Glaucoma follows immediatelt after when I take the option in qiestion 4, the questions under Cataract and Glaucoma are displayed.
I wish to have a formula in which once a service a selected it takes you directly to the service.
I also wish to know if there is a recall formula for previous questions, should a file (patient) be sent back to the unit it came from.
Thanks
Mathew
I hit pretty much the same issue when I was originally playing around with ODK Aggregate and setting up in my own VM to host it. Being too $cheap$ to pay for a real SSL cert for my dev VM, I wanted to use a self-signed cert instead [I suspect I'm not the only penny-pinching user out there... 
]. If there's interest I can post what it took to get ODK Collect (well, actually, Android itself!) to not barf when getting back my self-signed SLL cert.
