Using innerHTML to put a checkbox and an input field in a table cell

Hi all,

I need some help with some innerHTML code I am using to put a checkbox and an input field in a table cell. I have read in several places that the checkbox and input fields are not supposed to work when entered using innerHTML, but I have seen some examples on the Internet that do work.

By not working, I mean if I check the checkbox or try to enter a value in the input field, the check or value immediately disappears, and I can't use the value in my function.

Can someone please help me with my code? This is parred down to the minimum code required.
