I'm genuinely confused... Here is the refresh button in index:


What am I missing in all this, please?

Also, the debugger just shows:
127.0.0.1 - - [21/Jan/2021 19:29:35] "GET /refresh/False HTTP/1.1" 404 -

I'm confused, I have the same for my delete button but no URL issue, why do I have with almost the same steps?

#delete a product from the table
@app.route('/delete/', methods = ['GET', 'POST'])
def delete():
my_data = product_table.query.get(id)
db.session.delete(my_data)
db.session.commit()
flash("Stock/ETF Deleted Successfully")
return redirect(url_for('Index'))

Also, for the SQL, you mean:
SELECT
sum(portfolio_cost_total)
FROM
portfolio_table;
