WordPress randomly removing specific code from content

I have not found a solution specific to the code I’m using… Here’s what’s happening.

I edit my product in the text editor, and when I add a button for the product I add this code:

<form class=”signup” enctype=”multipart/form-data” method=”post”><button class=”single_add_to_cart_button button alt” name=”add-to-cart” type=”submit” value=”56″>Sign Up</button></form>

It works fine for a day or two but then I get clients complaining they can’t click the button, so I go back to check the editor and I find this code:

<button class=”single_add_to_cart_button button alt” name=”add-to-cart” type=”submit” value=”56″>Sign Up</button>

It seems to randomly remove the <form> code. I’m not sure what’s happening. The solutions that I have found are not specifically for <form> code.

Any idea, or suggestions, or solutions? It would be greatly appreciated!

Thank you!
