The parameter value will be captured when the form is generated and
will stay at that value as long as it's captured. Maybe I'm
misunderstanding what you mean, but I thought what you meant is that
you have a page with a query parameter "id", which has a form on it
generated by chooseIndex,
Capturing the value depends on reading it from the URL as a parameter,
so even if it's local, after I submit the form and the page reloads
without the "id" parameter in the URL, I still get the None.get error
because it is trying find a parameter that isn't there. I need some
way to keep the param
