Here is an example of code from a post:

But when it is pulled into the "category" page as an excerpt it gives this:

As you can see, it is pulling the start of the form, but not the rest.

I tried telling it to not strip <input type="hidden">, but when I went to save Atahaulpa cleared the field and just left <input type= in the field.
