HTML for add to cart on blog not saving correctly

[wesley312]

Hi I have a blog post where we are trying to add an "add to cart" button. we have previously used this code:

<form action="/cart/add" method="post"><input type="hidden" value="variant id"> <input type="submit" value="BUY NOW" name="add"></form>

When trying to enter on a new blog it is reverting to this and not functioning:

<form method="post" action="/cart/add">
<input value="variant id" type="hidden"> <input name="add" value="BUY NOW" type="submit">
</form

We did also recently switch themes which I am thinking has something to do with it.
