Please can someone help.

I've been dealling with this issue for weeks and can't seems to be able to make it work.

I'm trying to get the balance of token from a user address in a wallet. And all the code I've found online failed.

Please because this is fraustrating. The code is below.

    //let Web3 = require("web3");
        let userAdd = localStorage.getItem("userAddress");
        let currentAccount = null;
        let web3 = new Web3(new Web3.providers.HttpProvider("https://bsc-dataseed.binance.org"));
        //let web3 = new Web3("https://bsc-dataseed1.binance.org");
        let abi = [
  // balanceOf
  {
    "constant":true,
    "inputs":[{"name":"_owner","type":"address"}],
    "name":"balanceOf",
    "outputs":[{"name":"balance","type":"uint256"}],
    "type":"function"
  },
  // decimals
  {
    "constant":true,
    "inputs":[],
    "name":"decimals",
    "outputs":[{"name":"","type":"uint8"}],
    "type":"function"
  }
];
        let contactAddress = '0xd***************************';
      function handleAccountsChanged(accounts) {
            console.log('Calling HandleChanged')

            if (accounts.length === 0) {
                console.log('Please connect to MetaMask.');
                $('#enableMetamask').html('Connect with Metamask')
                localStorage.removeItem("userAddress", "");
            } else if (accounts[0] !== currentAccount) {
                currentAccount = accounts[0];
                $('#enableMetamask').html(currentAccount)
                $('#status').html('')

                if(currentAccount != null) {
                localStorage.setItem("userAddress", currentAccount);
                let strFirstThNum = currentAccount.substring(0,3);
                let strLastForNum = currentAccount.substr(currentAccount.length -4);
                let wallConAdd = ""+strFirstThNum+"...."+strLastForNum+"";
                $(".ui-udevwa").remove()

                $("#disbtnholder").html('<div id="signOutconnectedWallet" onclick="metamaskSignOut()" style="font-size:18px;color:#fff;text-align: center;margin:4px 0;padding:10px 6px;cursor:pointer;">Disconnect</div>');
      let balance;
  
                let contract = new web3.eth.Contract(abi,contactAddress);

async function getBalance() {
  balance = await contract.methods.balanceOf(userAdd).call();  
   balance = Web3.utils.fromWei(balance); // 29803630.997051883414242659
  return balance;
}
getBalance().then(function (result) {
    console.log(result);
