Having two DOM elements with the same name attribute is still valid (see
<input type="radio">.)
My main question is how does both the 'if' block and the 'else' block get
executed in the same pass through the function?

That is it.
That way only one of the two inputs of name="billable" get sent to the
handler on the server.
This page is a RT (request tracker) module and RT handles the processing
of the (server-side.) I would rather not modify the RT codebase to
handle the checkbox - I thought it could be done via JS.
My main questions still stands, how does both the 'if' and 'else' blocks
get executed on the same pass through the function?
Thanks for the time and help.
