Python Forex Calculator Not Complying
Question
I'm trying to complete a forex money converter in FLASK but my code isn't working. It allows the user input, then once I hit submit the next page that shows Method Not Allowed The method is not allowed for the requested URL.
-Update, now it just goes to an action page, whenever I try to pull up the Index2.html it doesn't load. I'm not sure why its not allowing me to proceed.
-I'm trying to save three inputs, add them to a list, then convert them into a dollar amount -Page Refreshes to action page, this is not what is intended

As index2.htlm is not shared, i created a simple 1 liner index2.html to show the conversion. PFB code:
app.py:
from flask import Flask, render_template, request, redirect, session, url_for
from forex_python.converter import CurrencyCodes, CurrencyRates
app = Flask(__name__)
app.config["secret key"] = "yeah"
app.config['DEBUG_TB_INTERCEPT_REDIRECTS'] = False
responses_key = "responses"
@app.route('/', methods = ['GET', 'POST'])
def index():
return render_template('Index.html')
T = CurrencyRates()
@app.route("/conversion", methods = ['GET', 'POST'])
def conversion():
if request.method == 'POST':
C1 = request.form.get('C1', None)
C2_to = request.form.get('C2_to', None)
amt = request.form.get('amt', None)
rate = T.convert(C1, C2_to, int(amt))
print(C1, C2_to, amt, rate)
details = {'C1': C1, 'C2_to': C2_to, 'amt': amt, 'rate': rate}
return render_template("Index2.html", details=details)
if __name__ == '__main__':
app.run(host='xx.xx.xx.xx', debug=True)
app.run(debug=True)
Index.html:
<!DOCTYPE html>
<html>
<body>
<h2>HTML Forms</h2>
<form action="{{ url_for('conversion') }}" method="post">
<label for="C1" name= "C1"> Converting From:</label><br>
<input type="text" id="C1" name="C1"><br>
<label for="C2_to" name= "C2_to">Converting To:</label><br>
<input type="text" id="C2_to" name="C2_to"><br>
<label for="amt">Amount:</label><br>
<input type="text" id="amt" name="amt"><br>
<br>
<input type="submit" value="Submit">
</form>
Index2.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
</head>
<body>
<p> Conversion of {{ details.amt }} {{ details.C1 }} to {{ details.C2_to }} is: {{ details.rate }}</p>
</body>
</html>
Output:
homepage:
conversion page:
