Why isn't my else in flask python not working?

Question

When I press the start button it directs me to error.html even if I choose my skin type

from flask import Flask, render_template, request

app = Flask(__name__)

SKIN = ["Oily" , "Dry" ,"Sensitive", "Combination", "Normal"]

@app.route("/")
def index():
   return render_template("index.html", skins=SKIN)

@app.route("/register", methods=["POST"])
def register():
   skin = request.form.get("skin")
   if not skin:
      return render_template("error.html")
   else:
      return render_template("info.html")

Answer 1

The problem I see is that your input is name="skin type" , whereas you are checking for an input named skin .

If you change the input to name="skin" it should work.

I also suggest in the future that you do not use spaces in any input field names.
