Add form to product detail page

-- HikaShop version -- : 3.2.2
-- Joomla version -- : 3.83.
-- PHP version -- : 7.1.12

HI,

I am using RSForms for my forms on the website.
I want to add a form to the bottom of the product detail page.
I have tried to add it to the bottom of the show_default.php file, but it seems that it then becomes a form within a form.
What happens is that when the submit button is pressed on the contact form you goto the checkout page.

I have tried to look and find how to get it outside the form of the product details page, but no luck.
Is there a way to do this?

Thanks,
Roger

I am sorry for the late response. I did try what you said and it worked for me.
Thank you.
