This is the function that gets called to create the checkbox...

var id_field = "src_over"+num;
var replace = "(Source Over?)<input type=checkbox id='"+id_field+"'
onClick='updateField("+id_field+")'>";
document.getElementById(str).innerHTML = replace;
}
And I get an error immediately after clicking the check box saying
something like:
Error: src_over10 is not defined
Its looking for the object or variable src_over10, you want it to pass
the string "src_over10".
So change this:
var replace = "(Source Over?)<input type=checkbox id='"+id_field+"'
onClick='updateField("+id_field+")'>";
To this:
var replace = "(Source Over?)<input type=checkbox id='"+id_field+"'
onClick='updateField(\'"+id_field+"\')'>";
Notice the two \' around the "+id_field+" , it's probably hard to see.
This will send the string "src_over10" to the updateField function,
which can be used with a getElementById.
You could also do this:
var replace = "(Source Over?)<input type=checkbox id='"+id_field+"'
onClick='updateField(this.id)'>";
Which will do the exact same thing, and save a millisecond or two.
