TypeError: int() argument must be a string or a number, not 'NoneType'

Hi,

I'm getting this error when I run the following code. Any help to solve it would be highly appreciated.

app.py code:

        
          
          
              
              from flask import Flask, render_template, jsonify,request,redirect,url_for
from random import randint
from top_block_22 import top_block_22
  
app = Flask(__name__)
@app.route('/')
def slide_func():
    return render_template("index.html")
  
@app.route('/valueofslider')
def slide():
    slide_val = request.form.get('slide_val')
    return main(slide_val)   
  
def main(slide_val):
    '''Code outside of route'''
    tb = top_block_22()
    tb.start()
    samp_rate = int(slide_val) + 100
    print(samp_rate)
    return(slide_val) # Still need to return or get TypeError   
  
if __name__ == '__main__':
    app.run(debug=True)

The problem with your code is that its not real code, its a picture of code, pictures of code cant be run.

If t was real code the value the variable slide_val is pointing contains None , int cannot turn None into a number.
