MODX

How to pass a value from a form and do I need to create a submit button for this, or is it enough just to enter a number

<div>
                <div>
                  <label>от</label>
                  <input id="area_from" name="area_from" type="text">
                </div>
                <div>
                  <label>до</label>
                  <input id="area_to" name="area_to" type="text">
                </div>
              </div>

to a snippet in a field instead of numbers &tvFilters=`area>=200,area<=400`
