Hi @elwyn ,
Will this work for you ?
import streamlit as st
emp = st.empty()
transport = emp.text_input('Transport', 0)
# Probably you don't need slider, just to show that the value can be variable user Input
val = st.slider(label = 'Transport value',min_value= 1,max_value = 20 )
if st.button('Set transport to 10'):
# Insted of val, just plug in 10, if exactly that's what you need
transport = emp.text_input('Transport', val)
Best,
Avra
