Storing responses in a list

Hi,

I developed an app for web scraping with user input. All the scraped links and documents in a list which is st.session_state.papers. When i am working locally the code is worked perfectly. However i deployed the app on Streamlit Cloud. When i click Next button, It is not appending the list which links are selected yes. I am begginer, maybe i am missing something.

Here is my code:

   if "count" not in st.session_state:
     st.session_state['count'] = 0

   if 'final_text' not in st.session_state:
      st.session_state.final_text = []
   if 'final_link' not in st.session_state:
      st.session_state.final_link = [] 


        def next_quote():
        st.session_state.count += 0
        if st.session_state.count == 7:
           st.session_state.count += 1
         
           index = st.session_state.count
          with st.form("my_form"):
               col1, col2 = st.columns(2)
               if st.session_state.papers:
                 if st.session_state.count < 7:
                   st.write("Progress: ", st.session_state.count + 1 , "/", 7)
                   text = st.session_state.papers[st.session_state.count]["Description"]
                   link = st.session_state.papers[st.session_state.count]["Link"]
                   CHOICES = {1: "Yes", 2: "No", 3: None}
                   def format_func(label):
                      return CHOICES[label]
                   label = st.selectbox("Select option", options=list(CHOICES.keys()), format_func=format_func)
                   st.write(link)
                   res_box = st.empty()
                   for i in range(len(text) + 1):
                      res_box.markdown(" %s" % text[0:i])
                      time.sleep(0.003)    
                   st.session_state.count += 1
                   with col2:
                     if st.form_submit_button("Next ⏭️", on_click=next_quote):
                       if st.session_state.count > 1:
                         if format_func(label) == "Yes":
                           st.session_state.final_text.append(st.session_state.papers[st.session_state.count - 2]["Description"])
                           st.session_state.final_link.append(st.session_state.papers[st.session_state.count - 2]["Link"])
                       if st.session_state == 2:   
                         if format_func(label)  == "Yes":
                           st.session_state.final_text.append(st.session_state.papers[0]["Description"])
                           st.session_state.final_link.append(st.session_state.papers[0]["Link"]) 
                 st.write(st.session_state.final_link)
                 st.write(st.session_state.count)
                 st.write(label)

st.session_state.final_link returning null on streamlit cloud. But the same code working in local perfectly.

hey hi ! welcome to the community !
there some minor mistakes in your code hope this fix it !

import streamlit as st
import time

if "count" not in st.session_state:
    st.session_state['count'] = 0

if 'final_text' not in st.session_state:
    st.session_state.final_text = []

if 'final_link' not in st.session_state:
    st.session_state.final_link = []

def next_quote():
    st.session_state.count += 1
    if st.session_state.count == 7:
        st.session_state.count += 1

    index = st.session_state.count
    with st.form("my_form"):
        col1, col2 = st.columns(2)
        if st.session_state.papers:
            if st.session_state.count < 7:
                st.write("Progress: ", st.session_state.count + 1, "/", 7)
                text = st.session_state.papers[st.session_state.count]["Description"]
                link = st.session_state.papers[st.session_state.count]["Link"]
                CHOICES = {1: "Yes", 2: "No", 3: None}

                def format_func(label):
                    return CHOICES[label]

                label = st.selectbox("Select option", options=list(CHOICES.keys()), format_func=format_func)
                st.write(link)
                res_box = st.empty()
                for i in range(len(text) + 1):
                    res_box.markdown(" %s" % text[0:i])
                    time.sleep(0.003)

                st.session_state.count += 1

                with col2:
                    if st.form_submit_button("Next ⏭️", on_click=next_quote):
                        if st.session_state.count > 1:
                            if format_func(label) == "Yes":
                                st.session_state.final_text.append(
                                    st.session_state.papers[st.session_state.count - 2]["Description"]
                                )
                                st.session_state.final_link.append(
                                    st.session_state.papers[st.session_state.count - 2]["Link"]
                                )

                        if st.session_state.count == 2:
                            if format_func(label) == "Yes":
                                st.session_state.final_text.append(st.session_state.papers[0]["Description"])
                                st.session_state.final_link.append(st.session_state.papers[0]["Link"])

        st.write(st.session_state.final_link)
        st.write(st.session_state.count)
        st.write(label)
