Maybe someone can tell me how i can repair problem with choosing from Paypal/Bitcoin/Credit Card, coz i tried almost everything, getting through google, MDN, StackOverflow, asked even on Slack (i did not receive valuable help).

The problem is in that : (That's like 1000000 version that i tried)

// checking payment options

$paymentOptionsCard.change(()=>{

// if credit card if($paymentOptions.val()==='Credit Card'){ $creditCard.show(); bullPay = true; } else{ $creditCard.hide(); bullPay = false; } });

$paymentOptionsPaypal.change(()=>{ if($paymentOptionsPaypal.val()==="PayPal"){ $paypal.show(); bullPay = true; } else{ $paypal.hide(); bullPay = false; }});

$paymentOptionsBitcoin.change(()=>{ //if bitcoin if($paymentOptionsBitcoin.val()==="Bitcoin"){ $bitcoin.show(); bullPay = true; } else{ $bitcoin.hide(); bullPay = false; } });

and that's the variables

//getting payment options const $paymentOptions = $("#payment"); //selecting default as Credit card

const $paymentOptionsBitcoin = $paymentOptions.val("Bitcoin"); const $paymentOptionsPaypal = $paymentOptions.val("PayPal"); const $paymentOptionsCard = $paymentOptions.val("Credit Card");

HTML from where i get that variables:

  <select id="payment" name="user-payment">
      <option value="select method">Select Payment Method</option>
      <option value="Credit Card">Credit Card</option>
      <option value="PayPal">PayPal</option>
      <option value="Bitcoin">Bitcoin</option>
    </select>
