Im working on building a small JS event on my website doing all the changes through website/customize/html/css/js editior
now i check many times my code has no issues and was working fine so far but when i cleared browser stored cookies, site data, and cache the js event doesn't work anymore now I'm not that good at debugging for js but in the developers tool/network i can see some most of the things are not loading now i dont know if that might be the issue 
any helps would be appreciated 

thankyou
