Javascript if/else

The following script works fine (i am not familiar with Javascript). I wish to change the para.textcontent to display a form (paypal button). if I inset the form in the para.textconten field it does not work. Any help? I have shown the button code below the script.

                      <label for="weather">Select the weather type today: </label>
                      <select id="weather">
                          <option value="">--Make a choice--</option>
                              <option value="sunny">Sunny</option>
                              <option value="rainy">Rainy</option>
                              <option value="snowing">Snowing</option>
                              <option value="overcast">Overcast</option>


                              const select = document.querySelector('select');
                              const para = document.querySelector('p');

                              select.addEventListener('change', setWeather);

                              function setWeather() {
                                  const choice = select.value;

                                 if (choice === 'sunny') {
                                     para.textContent = 'It is nice and sunny outside today. Wear shorts! Go to the beach, or the park, and get an ice cream.';
                                     } else if (choice === 'rainy') {
                                      para.textContent = 'Rain is falling outside; take a rain coat and an umbrella, and don\'t stay out for too long.';
                                     } else if (choice === 'snowing') {
                                      para.textContent = 'The snow is coming down — it is freezing! Best to stay in with a cup of hot chocolate, or go build a snowman.';
                                     } else if (choice === 'overcast') {
                                     para.textContent = 'It isn\'t raining, but the sky is grey and gloomy; it could turn any minute, so take a rain coat just in case.';
                                     } else {
                                       para.textContent = '';

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).

OK, but how do I insert the form code into the else statement?
