Pass values in flask from a form to a table using redirection

I am working on this app, which has a form where you input the name, choose a value from a dropbox, and select one or more items from a checkbox. I need to redirect the values of this form to another page and format them to a table. I am new to programming, and want to get the values from the add form and format them into a table in the tally form. Here are my code snippets:

@app.route('/add', methods=['POST','GET'])
def add():
    if request.method == 'POST':
        plan_name = request.form
        formation_name = request.form
        variation_name = request.form
        return redirect('/tally')

    return render_template('add.html')
@app.route('/tally', methods=['Get','POST'])
def tally():


    return render_template('tally.html')



<form action='/add' method='POST'>
<h1>Enter a name for your gameplan:</h1>
  <div class="form-group row">
    <label for="plan" name = 'plan_name'value = '{{request.form['name']}}' class="col-sm-2 col-form-label">Name:</label>
    <div class="col-sm-10">
      <input type="text" >
    </div>
  </div>
<p><h1>Choose Your Formation<p></h1>
 <div class="form-row align-items-center">
    <div class="col-auto my-1">
      <select class="custom-select mr-sm-2" id="inlineFormCustomSelect">
        <option selected>Choose...</option>
        <option name = "formation_name" >Doubles</option>
      </select>
    </div>
  </div>

<p><h1>Select The Variation</h1></p>
 <div class="form-group row">
    <div class="col-sm-2">Select one or many:</div>
    <div class="col-sm-10">
