Hey @MelD78 

Welcome to the community

Step 1 - you need to get your Klaviyo signup form HTML code

• Log in to your Klaviyo account. Navigate to the "Signup Forms" tab.
• Create a new signup form or use an existing one. Customize the form according to your requirements. After customizing, save the form.
• After saving the form, click on the "Embed" button.
• Copy the HTML embed code provided by Klaviyo.

Step 2: Modify the Prestige Theme Footer

• Find the Prestige theme and click on "Actions" > "Edit Code."
• In the theme editor, navigate to the "Sections" folder and find the footer.liquid file or a similarly named file that contains the footer code. Locate the existing form or the section where you want to add the Klaviyo form.
• Paste the Klaviyo form embed code you copied earlier. Remove the existing form HTML code (if any).

Step 3: Customize the Subscribe Button

• In the Klaviyo embed code, find the <button> tag or the submit button for the form.

• You can add custom CSS to style the button to match your theme. You can do this within the Klaviyo embed code or in your theme's CSS file (theme.scss.liquid or theme.css.liquid). 

• Make sure the form action URL points to Klaviyo, and the form is correctly set up to add subscribers to your desired list.

Step 4 - Just save the form and test it. 

Let me know if this worked. I hope this helps
