Remove all those tab indexes. The form fails to work at all with a mouse.
Review HTML forms
Also, fix your code errors.
Thanks. I took out all the tabindexes, and the demographic part of the form works, but the cursor still jumps back to the first field in the form when a radio button is clicked. Is there an onclick property I need to set?
No onclick necessary. Something else is obviously wrong with your form code. Did you fix your code validation errors yet?
